FIELD OF THE INVENTION
The present invention relates to the field of footwear or other foot-receiving devices, e.g., including various conforming fit, stability, and/or “locked down” feel features.
BACKGROUND
Conventional articles of athletic footwear include two primary elements, an upper and a sole structure. The upper may provide a covering for the foot that securely receives and positions the foot with respect to the sole structure. In addition, the upper may have a configuration that protects the foot and provides ventilation, thereby cooling the foot and removing perspiration. The sole structure may be secured to a lower surface of the upper and generally is positioned between the foot and any contact surface. In addition to attenuating ground reaction forces and absorbing energy, the sole structure may provide traction and control potentially harmful foot motion, such as over pronation.
The upper forms a void on the interior of the footwear for receiving the foot. The void has the general shape of the foot, and access to the void is provided at an ankle opening. Accordingly, the upper extends over the instep and toe areas of the foot, along the medial and lateral sides of the foot, and around the heel area of the foot. A lacing system often is incorporated into the upper to allow users to selectively change the size of the ankle opening and to permit the user to modify certain dimensions of the upper, particularly girth, to accommodate feet with varying proportions. In addition, the upper may include a tongue that extends under the lacing system to enhance the comfort of the footwear (e.g., to modulate pressure applied to the foot by the laces). The upper also may include a heel counter to limit or control movement of the heel.
“Footwear,” as that term is used herein, means any type of wearing apparel for the feet, and this term includes, but is not limited to: all types of shoes, boots, sneakers, sandals, thongs, flip-flops, mules, scuffs, slippers, sport-specific shoes (such as golf shoes, tennis shoes, baseball cleats, soccer or football cleats, ski boots, basketball shoes, cross training shoes, etc.), and the like. “Foot-receiving device,” as that term is used herein, means any device into which a user places at least some portion of his or her foot. In addition to all types of “footwear,” foot-receiving devices include, but are not limited to: bindings and other devices for securing feet in snow skis, cross country skis, water skis, snowboards, and the like; bindings, clips, or other devices for securing feet in pedals for use with bicycles, exercise equipment, and the like; bindings, clips, or other devices for receiving feet during play of video games or other games; and the like. “Foot-receiving devices” may include: (a) one or more “foot-covering members” (e.g., akin to footwear upper components), which help position the foot with respect to other components or structures, and (b) one or more “foot-supporting members” (e.g., akin to footwear sole structure components), which support at least some portion(s) of a plantar surface of a user's foot. “Foot-supporting members” may include components for and/or functioning as midsoles and/or outsoles for articles of footwear (or components providing corresponding functions in non-footwear type foot-receiving devices).

I. GENERAL DESCRIPTION OF ASPECTS OF THIS INVENTION
As noted above, aspects of this invention relate to the field of footwear or other foot-receiving devices, e.g., including various conforming fit, stability, and/or “locked down” feel features.
Some aspects of this invention relate to uppers (or foot-covering components) for articles of footwear (or other foot-receiving devices) that include: (a) an upper shell defining an interior chamber, wherein the upper shell includes a plantar support surface and sidewalls extending upward from an outer perimeter of the plantar support surface; and (b) a bootie component (which may be formed as a sock or sock-like garment that optionally fits tightly to and/or conforms in shape to a wearer's foot) received in the interior chamber. In at least some examples of this aspect of the invention, the bootie component may be fixedly engaged with the upper shell at fixed connections that include (and optionally consist essentially of):
- (a) one or more fixed bottom connections between the bootie component (e.g., its bottom surface) and the plantar support surface of the upper shell, wherein the one or more fixed bottom connections is/are spaced inward (e.g., at least 6 mm) from the outer perimeter of the plantar support surface, and
- (b) one or more fixed top connections between the bootie component and a top forefoot area of the upper shell, wherein each of the one or more fixed top connections is located within a fixed region having: (i) a width dimension of less than 5 cm in a medial side-to-lateral side direction of the upper and a length dimension of less than 2 cm in a heel-to-toe direction of the upper and/or (ii) a fixed area of less than 10 cm2.
Some additional or alternative aspects of this invention relate to uppers (or foot-covering components) for articles of footwear (or other foot-receiving devices) that include: (a) an upper shell defining an interior chamber and a lace engaging region, wherein the upper shell includes a plantar support surface and sidewalls extending upward from an outer perimeter of the plantar support surface; and (b) a bootie component (which may be formed as a sock or sock-like garment that optionally fits tightly to and/or conforms in shape to a wearer's foot) received in the interior chamber.

- (b) a top of the bootie component is fixedly engaged with the top panel at a fixed region located proximate to the forward edge of the lace engaging region, wherein the fixed region has: (i) a width dimension of less than 5 cm in a medial side-to-lateral side direction of the upper and a first length dimension of less than 2 cm in a heel-to-toe direction of the upper and/or (ii) a fixed area of less than 10 cm2,
- (c) the top of the bootie component is not fixedly engaged with the top panel at a non-fixed region located forward of the fixed region, wherein the non-fixed region has: (i) a second length dimension of at least 2 cm in the heel-to-toe direction of the upper and/or a non-fixed area of at least 10 cm2,
- (d) the bootie component is not fixedly engaged with the medial sidewall, and/or
- (e) the bootie component is not fixedly engaged with the lateral sidewall.
In this manner, the bootie component may be substantially decoupled from the upper shell, e.g., at least along the sides of the bootie component/upper shell/upper.
Additional or alternative aspects of this invention relate to uppers (or foot-covering components) for articles of footwear (or other foot-receiving devices) that include one or more foot wrapping bands (e.g., on the medial side and/or the lateral side of the upper or foot-covering component). The foot wrapping band(s) may include:
- a first medial side foot wrapping band that includes: (a) a first medial lace engaging element, (b) a first medial band segment extending from the first medial lace engaging element and optionally between an upper shell and a bootie component of the upper, wherein the first medial band segment is engaged with a plantar support surface of the upper (e.g., an upper shell) at a fixed bottom connection spaced inward from an outer perimeter of the plantar support surface, and (c) a second medial band segment extending from the first medial lace engaging element and optionally between an upper shell and a bootie component of the upper, wherein the second medial band segment extends forward of the first medial band segment and is engaged with a plantar support surface of the upper (e.g., an upper shell) at a fixed bottom connection spaced inward from an outer perimeter of the plantar support surface; and/or
- a first lateral side foot wrapping band that includes: (a) a first lateral lace engaging element, (b) a first lateral band segment extending from the first lateral lace engaging element and optionally between an upper shell and a bootie component of an upper, wherein the first lateral band segment is engaged with a plantar support surface of the upper (e.g., an upper shell) at a fixed bottom connection spaced inward from an outer perimeter of the plantar support surface, and (c) a second lateral band segment extending from the first lateral lace engaging element and optionally between an upper shell and a bootie component of the upper, wherein the second lateral band segment extends forward of the first lateral band segment and is engaged with a plantar support surface of the upper (e.g., an upper shell) at a fixed bottom connection spaced inward from an outer perimeter of the plantar support surface.
Optionally, at least one of the first medial band segment, the second medial band segment, the first lateral band segment, and/or the second lateral band segment will have a thin, flat band structure, e.g., less than 5 mm thick, and in some examples, less than 4 mm thick or even less than 3 mm thick. As some more specific examples, at least one of the first medial band segment, the second medial band segment, the first lateral band segment, and/or the second lateral band segment will have a longitudinal length L, a width W, and a thickness T, wherein:
T≥1 mm, W≥3T, and L≥10W.
Uppers (or foot-covering components) according to aspects and/or examples of the invention having foot wrapping bands may include any desired number of foot wrapping bands on the medial side (e.g., from 1 to 10, and in some examples a plurality of such medial foot wrapping bands, e.g., from 2 to 8 or even from 2 to 6) and/or any desired number of foot wrapping bands on the lateral side (e.g., from 1 to 10, and in some examples, a plurality of such lateral foot wrapping bands, e.g., from 2 to 8 or even from 2 to 6). Any one or more of these foot wrapping bands may have the longitudinal length, width, and/or thickness dimensional features described above. When two or more of the foot wrapping bands are provided on one side of the upper/foot-covering component, segments of the foot wrapping bands (e.g., segments of adjacent foot wrapping bands) may cross one another. The foot wrapping band(s) may form a “V” shaped configuration, e.g., to contain and/or support a side of the wearer's foot, e.g., in which the vertex of the “V” shape constitutes the lace engaging element.
Additionally or alternatively, uppers/foot-covering components according to at least some aspects of this invention may include one or both of:
- a rearmost medial side foot wrapping band that includes: (a) a medial lace engaging element, (b) a rearward extending medial band segment extending from the medial lace engaging element and optionally between an upper shell and a bootie component of the upper, wherein the rearward extending medial band segment is engaged with a rear heel area of the upper (e.g., with a rear heel area of a bootie component), and (c) another medial band segment extending from the medial lace engaging element and optionally between an upper shell and a bootie component of the upper, wherein this other medial band segment extends forward of the rearward extending medial band segment and is engaged with a plantar support surface of the upper (e.g., an upper shell) at a fixed bottom connection spaced inward from an outer perimeter of the plantar support surface; and/or
- a rearmost lateral side foot wrapping band that includes: (a) a lateral lace engaging element, (b) a rearward extending lateral band segment extending from the lateral lace engaging element and optionally between an upper shell and a bootie component of the upper, wherein the rearward extending lateral band segment is engaged with a rear heel area of the upper (e.g., with a rear heel area of a bootie component), and (c) another lateral band segment extending from the lateral lace engaging element and optionally between an upper shell and a bootie component of the upper, wherein this other lateral band segment extends forward of the rearward extending lateral band segment and is engaged with a plantar support surface of the upper (e.g., an upper shell) at a fixed bottom connection spaced inward from an outer perimeter of the plantar support surface.
The rearmost foot wrapping band(s) may form a “V” shaped configuration, e.g., to contain and/or support a side and/or heel area of a wearer's foot, e.g., in which the vertex of the “V” shape constitutes the lace engaging element. Either or both of these rearmost foot wrapping bands may have any of the various dimensional, shape, and/or structural features described above for the other foot wrapping bands.
Uppers and/or foot-covering components in accordance with still additional or other alternative aspects of this invention may include an interior compartment defined by the bootie component configured to completely contain a wearer's foot (e.g., akin to a sock like structure), wherein the upper further comprises an interior midsole received in the interior compartment of the bootie component, wherein the interior midsole includes a plantar support surface and is made from a polymer foam material. This interior midsole, when present, may define a longitudinal direction extending from a rearmost heel location to a forwardmost toe location, wherein along the longitudinal direction, a thickest dimension of the interior midsole along the longitudinal direction may be located in a forward heel and/or an arch support area of the interior midsole. This interior midsole may be removably received in the interior compartment of the upper/foot-covering component (e.g., inside the bootie component and/or closest to a plantar surface of a wearer's foot).
Additional aspects of this invention relate to articles of footwear (or other foot-receiving devices) that include uppers (or foot-covering components) according to any of the aspects of the invention described above (or those described in more detail below) and a sole structure (or other foot-supporting component) engaged with the upper (or foot-covering component).
Given the general description of example features, aspects, structures, and arrangements according to certain embodiments of the invention provided above, a more detailed description of specific example footwear upper structures, articles of footwear, foot-receiving devices, and methods in accordance with this invention follows.
II. DETAILED DESCRIPTION OF EXAMPLE ARTICLES OF FOOTWEAR AND OTHER COMPONENTS/FEATURES ACCORDING TO THIS INVENTION
FIGS. 1A-1D provide various views of an example article of footwear 100 in accordance with at least some aspects of this invention. FIG. 1A provides a medial side view of the article of footwear 100, FIG. 1B provides a lateral side view, FIG. 1C provides a top view, and FIG. 1D provides a bottom view. This example article of footwear 100 includes an upper 102 and a sole structure 104 engaged with the upper 102. While articles of footwear 100 in accordance with aspects of this invention may be designed for any desired type of end use, in this specifically illustrated example, the article of footwear 100 is designed for use in playing tennis.
The sole structure 104 of this illustrated example includes a midsole 104M and an outsole 104O, e.g., engaged with the midsole 104M. The midsole 104M absorbs energy and provides impact force attenuation and may be configured to support an entire plantar surface of a wearer's foot. The midsole 104M may be made from any desired materials, including materials conventionally known and used in the footwear arts, such as polyurethane foams, ethylvinylacetate foams, and the like. Additionally or alternatively, the midsole 104M may be made from one or more parts and may include other impact force attenuating structures, such as one or more of: one or more fluid-filled bladders, one or more mechanical shock absorbers, etc. The outsole 104O provides traction and wear resistance and may be made from one or more parts. The outsole 104O may be made from any desired materials, including materials conventionally known and used in the footwear arts, such as thermoplastic polyurethanes, rubbers, and the like. If desired, the outsole 104O may be omitted at least at some locations at the bottom of the footwear 100 structure and/or the midsole 104M may function as the outsole at least at some locations. Alternatively, if desired, the midsole 104M may be omitted at least at some locations of the footwear 100 structure and/or the outsole 104O may function as the midsole at least at some locations. The midsole 104M and/or the outsole 104O may include grooves, flex lines, or the like, e.g., to enhance flexibility and/or natural motion of the sole structure 104, to provide traction, etc.
The components and structure of the upper 102 according to this specifically illustrated example of the invention now will be described in more detail with additional reference to FIG. 2A (a cross sectional view of an example footwear structure 100). The upper 102 of this example includes two main components (each of which may be made from one or more parts), namely an upper shell 110 and a bootie component 120. The upper shell 110 of this example, which may be made from one or more parts, includes a plantar support surface 110S, a lateral sidewall 110L, and a medial sidewall 110M. Each of the lateral sidewall 110L and the medial sidewall 110M extends upward from an outer perimeter 110P of the plantar support surface 110S. In this manner, the upper shell 110 defines an interior chamber 110C into which the bootie component 120 is received.
The upper shell 110 of this example is made from multiple component parts. One main part is a textile and/or polymeric component 110X forming much of the lateral sidewall 110L, the medial sidewall 110M, and the top panel 112, e.g., over the instep and/or forefoot containing area of the upper 102. A heel support 114 is provided around the heel area of the upper shell 110, e.g., to provide additional support for the heel area of a wearer's foot. The heel support 114 may be made from a stiffer or less flexible material than the textile/polymeric component 110X, e.g., from a rubber or thermoplastic polyurethane material. The heel support 114 may constitute a heel counter structure, if desired. The interior heel area of the upper shell 110 may include foam and/or gel type pads or comfort-enhancing components 114P, e.g., that comfortably engage and/or conform in shape to the wearer's ankle (note also FIG. 4F). The medial side of the forward toe and forefoot area of this example upper shell 110 includes a wear resistant component 110W, which in this example may be made of a plastic material (e.g., a thermoplastic polyurethane, a rubber material, etc.). This wear resistant component 110W is useful in this example footwear 100 structure to provide additional protection for the “big toe” area of the upper 102, which can receive substantial wear when playing tennis (e.g., during serves, when changing direction, etc.). Additionally, if desired, the outer surface of the wear resistant component 110W may include traction elements 110T, e.g., made of rubber or other “gripping” material, to provide additional traction at appropriate times (e.g., during a serve, etc.). The traction elements 110T are provided as small round “dots” of traction enhancing material in this illustrated example.
As mentioned above, in this example upper 102 structure, a bootie component 120 is received in the interior chamber 110C defined (at least in part) by the upper shell 110. In this example, the bootie component 120 has a “sock-like” configuration, e.g., made from a knit material, that closely receives, engages, and conforms in shape to the wearer's foot. Optionally, the bootie component 120 may be made by a circular knitting procedure and/or from a material that provides a relatively tight and optionally compression fit against the wearer's foot. The bootie component 120 may include one or more of: cottons; polyesters; Lycra, elastane, and/or other elastic materials; etc. The bootie component 120 of this example defines an interior chamber 120C into which the wearer's foot is received.
FIGS. 1E and 2A illustrate example engagement of the bottom 120B of the bootie component 120 with the plantar support surface 110S of the upper shell 110. FIG. 1E illustrates a bottom surface of the upper shell 110 and FIG. 2A is a cross sectional view of the article of footwear 100. As shown in these figures, the bottom 120B of the bootie component 120 is fixed to the plantar support surface 110S of the upper shell 110 by a sewn seam 130S that in this example extends completely around the plantar support surface 110S as a complete loop (e.g., in an hourglass type shape). The sewn seam 130S is located inward from the outer perimeter 110P of the plantar support surface 110S. Connections of this general type are described, for example, in co-pending U.S. patent application Ser. No. 14/927,751; U.S. Pat. Nos. 9,609,908; 9,210,866; and 8,578,632, each of which is entirely incorporated herein by reference, and the connections shown in these patent documents can be used in conjunction with footwear structures 100 in accordance with at least some examples of this invention. As shown in FIG. 1E, the sewn seam 130S may be spaced inward from the outer perimeter edge 110P of the plantar support surface 110S by an inward spacing distance (e.g., distances D4 to D7 shown in FIG. 1E). This inward spacing distance may vary over the path of the sewn seam 130S, e.g., varying between 6 mm to 40 mm, and in some examples, between 6 mm and 25 mm. In at least some examples of this invention, the inward spacing distance (e.g., D4 to D7) may be at least 6 mm over at least 75% of an overall path of the seam 130S. As some additional or alternative potential features, the inward spacing distance (e.g., D4 to D7) may be: (a) at least 12 mm over at least 75% of an overall path of the seam 130S, (b) at least 6 mm over at least 80% of an overall path of the seam 130S, (c) at least 12 mm over at least 80% of an overall path of the seam 130S, (d) at least 6 mm over at least 90% of an overall path of the seam 130S, (e) at least 12 mm over at least 90% of an overall path of the seam 130S, (f) at least 6 mm over at least 95% of an overall path of the seam 130S, and/or (g) at least 12 mm over at least 95% of an overall path of the seam 130S.
While FIG. 1E shows the sewn seam 130S extending completely around the plantar support surface 110S to form an inwardly spaced closed loop, other options are possible without departing from this invention. For example, if desired, one or more breaks may be provided in the sewn seam (see FIG. 1F, thereby producing seam segments). In this manner, support and coupling between the bootie component 120 and the upper shell 110 can be provided where needed or desired and a more “decoupled” structure can be provided at other locations. Any desired number of seam 130S segments and/or seam breaks around the plantar support surface 110S can be provided without departing from the invention. The seam segments of FIG. 1F can have any of the inward spacing features (e.g., D4 to D7) described above. Additionally or alternatively, if desired, rather than or in addition to the sewn seam 130S, the bottom of bootie component 120 may be fixed with the plantar support surface 110S of the upper shell 110 by adhesives or cements and/or by mechanical connectors without departing from this invention.
The bootie component 120 may be fixed with the upper shell 110 in other manners and/or in other areas as well. In at least some examples of this invention, the bootie component 120 may be fixedly engaged with the upper shell 110 at fixed connections that include (and optionally consist essentially of):
- (a) one or more fixed bottom connections (e.g., shown by loop seam 130S and/or seam segments 130S in FIGS. 1E and 1F) between the bootie component 120 and the plantar support surface 110P of the upper shell 110, wherein the one or more fixed bottom connections is/are spaced inward (distances D4-D7), e.g., at least 6 mm, from the outer perimeter 110P of the plantar support surface 110S (the fixed bottom connection(s) may have any of the inward spacing features described above), and
- (b) one or more fixed top connections (e.g., using one or more of adhesives, stitching, mechanical fasteners, etc.) between the bootie component 120 and a top forefoot area (e.g., within top panel 112) of the upper shell 110, wherein each of the one or more fixed top connections is located within a fixed region 112R (see FIG. 1C) having: (i) a width dimension W (e.g., at a location of greatest width) of less than 5 cm in a medial side-to-lateral side direction (direction 22, see FIG. 1E, which is perpendicular to heel-to-toe direction 20 in FIG. 1E) of the upper 102 and/or the upper shell 110 and a length dimension L (e.g., at a location of greatest length) of less than 2 cm in a heel-to-toe direction (direction 20 from the rearmost heel location RH to a forwardmost toe location FT, see FIG. 1E) of the upper 102 and/or the upper shell 110 and/or (ii) a fixed area of less than 10 cm2.
In at least some examples of this aspect of the invention, the top of the bootie component 120 will not be fixedly engaged with the top forefoot area of the upper shell 110 (e.g., not fixed to the inside surface of top panel 112) at a non-fixed region 116 located forward of the fixed region 112R. Optionally, this non-fixed region 116 may have: (i) a second length dimension L2 of at least 2 cm in the heel-to-toe direction of the upper 102 and/or upper shell 110 and/or (ii) a non-fixed area of at least 10 cm2. Additionally or alternatively, the bootie component 120 need not be fixedly engaged with a medial side 110M of the upper shell 110 and/or the bootie component 120 need not be fixedly engaged with a lateral side 110L of the upper shell 110. The non-fixed region 116 may help allow the sock-like bootie component 120 conform to the wearer's foot and may help maintain a secure, “locked-down” feel of the upper 102.
The fixed top connection(s) in these aspects or examples of the invention may have any one or more of the following properties: (a) a width dimension W (e.g., at a location of greatest width) of less than 4 cm in a medial side-to-lateral side direction, (b) a width dimension W (e.g., at a location of greatest width) of less than 3 cm in a medial side-to-lateral side direction, (c) a width dimension W (e.g., at a location of greatest width) of less than 2.5 cm in a medial side-to-lateral side direction, (d) a length dimension L (e.g., at a location of greatest length) of less than 1.75 cm in a heel-to-toe direction, (e) a length dimension L (e.g., at a location of greatest length) of less than 1.5 cm in a heel-to-toe direction, (f) a length dimension L (e.g., at a location of greatest length) of less than 1 cm in a heel-to-toe direction, (g) a fixed area of fixed region 112R of less than 8 cm2, (h) a fixed area of fixed region 112R of less than 6 cm2, and/or (i) a fixed area of fixed region 112R of less than 5 cm2.
Additionally or alternatively, when present, the non-fixed region 116 forward of the fixed region 112R in these aspects or examples of the invention may have any one or more of the following properties: (a) a width dimension W2 (e.g., at a location of greatest width) of at least 3 cm in a medial side-to-lateral side direction, (b) a width dimension W2 (e.g., at a location of greatest width) of at least 4 cm in a medial side-to-lateral side direction, (c) a width dimension W2 (e.g., at a location of greatest width) of at least 5 cm in a medial side-to-lateral side direction, (d) a length dimension L2 (e.g., at a location of greatest length) of at least 2.5 cm in a heel-to-toe direction, (e) a length dimension L2 (e.g., at a location of greatest length) of at least 3.5 cm in a heel-to-toe direction, (f) a length dimension L2 (e.g., at a location of greatest length) of at least 4 cm in a heel-to-toe direction, (g) a non-fixed area of non-fixed region 116 of at least 12 cm2, (h) a non-fixed area of non-fixed region 116 of at least 15 cm2, (i) a non-fixed area of non-fixed region 116 of at least 18 cm2, and/or (j) a non-fixed area of non-fixed region 116 of at least 21 cm2.
FIGS. 2A-2C show further features that may be included in uppers 102 (or foot-covering components) and/or articles of footwear 100 (or other foot-receiving devices) in accordance with at least some examples of this invention. As shown in these figures, an interior midsole 140 is provided within the foot-receiving chamber 120C of the bootie component 120. The top surface 140S of the interior midsole 140 may be contoured to correspond to the shape of a wearer's foot, and if desired, the outer edges 140E may curve upward somewhat, e.g., to help stably position the wearer's foot on the top surface 140S. The interior midsole 140 may be inserted into the foot-receiving chamber 120C of the bootie component 120, e.g., as shown in FIG. 2C, so that the interior midsole 140 will be in direct contact with and/or the closest footwear 100 component to a plantar surface of a wearer's foot. The interior midsole 140 may be made of a foam material, e.g., a lightweight foam material, made from polyurethane foam, ethylvinylacetate foam, and/or other foam materials. The interior midsole 140 may be thickest (e.g., the dimension from its top surface 140S to its bottom surface 140B) at a forward heel support area and/or a midfoot/arch support area of the midsole 140 (e.g., between lines 142A and 142B in FIG. 2B).
The interior midsole 140 of this example footwear 100 structure may be somewhat thicker than conventional footwear insoles and/or sockliners. As some more specific examples, the interior midsole 140 may have: (a) a thickness of at least 6 mm through at least 50% of its top surface 140S (measuring directly from the top surface 140S to the bottom surface 140B), (b) a thickness of at least 6 mm through at least 70% of its top surface 140S, (c) a thickness of at least 6 mm through at least 80% of its top surface 140S, (d) a thickness of at least 6 mm through at least 90% of its top surface 140S, (e) a thickness of at least 9 mm through at least 50% of its top surface 140S, (f) a thickness of at least 9 mm through at least 70% of its top surface 140S, and/or (g) a thickness of at least 11 mm through at least 50% of its top surface 140S. The foam material of the interior midsole 140, its thickness, and its location directly beneath the wearer's foot enhance comfort of the overall footwear 100 structure of this specific example. In addition, the raised outer edges 140E of the interior midsole 140 can help moderate the feel of the foot wrapping band(s) 200, which will be described in more detail below. The location of this example interior midsole 140 (i.e., between the wearer's foot and the location where the foot wrapping bands 200 are connected to the upper shell 110) can help improve comfort and moderate wearer feel/awareness of the foot wrapping bands 200, especially when a lace 300 pulls the foot wrapping bands 200 tight (as will be described in more detail below).
While the interior midsole 140 of this illustrated example is removable from the interior chamber 120C of the bootie component 120, other options are possible. For example, if desired, the interior midsole 140 could be fixed within the interior chamber 120C, e.g., by adhesives, mechanical connectors (e.g., hook-and-loop fasteners), sewn seams, etc. Additionally or alternatively, if desired, a midsole component (e.g., foam, fluid-filled bladder(s), etc.) may be provided between the bootie component 120 and the upper shell 110, e.g., in place of and/or in addition to an interior midsole 140 in the interior chamber 120C of the bootie component 120.
FIGS. 3A-4G illustrate various potential features of foot wrapping bands 200 that may be included in articles of footwear 100 in accordance with at least some examples of this invention. As shown in these figures, each side (i.e., the lateral side and the medial side) of the article of footwear 100 includes at least one foot wrapping band 200, and optionally a plurality of foot wrapping bands 200 on each side. Note also FIGS. 1A-1C and 2A. The wrapping band(s) 200 of these illustrated examples include a lace engaging element 202L (e.g., in a generally central area of the band 200), (b) a rearwardly extending band segment 202R extending from the lace engaging element 202L (optionally extending between the upper shell 110 and the bootie component 120), and (c) a forwardly extending band segment 202F extending from the lace engaging element 202L (optionally between the upper shell 110 and the bootie component 120). Optionally, the rearwardly extending band segment 202R may be engaged with the plantar support surface 110S of the upper shell 110 at a fixed bottom connection spaced inward from the outer perimeter 110P of the plantar support surface 110S and/or the forwardly extending band segment 202F extends forward of the rearwardly extending band segment 202R and may be engaged with the plantar support surface 110S at a fixed bottom connection spaced inward from the outer perimeter 110P of the plantar support surface 110S. If desired, the band segment(s) 202R and/or 202F may be engaged with the plantar support surface 110S at location(s) spaced inward from the outer perimeter 110P of the plantar support surface 110S using the same fixed connection as used to engage the plantar support surface 110S with the bootie component 120 (e.g., sewn seam 130S, adhesives or cements, mechanical fasteners, etc.). As shown in FIGS. 1A-1C, the lace engaging element 202L extends through the openings in the upper components 110M, 110L and form a loop through which the lace 300 extends.
FIGS. 3A-3D show additional potential features of foot wrapping bands 200 that may be included in articles of footwear 100 in accordance with at least some examples of this invention. As shown in these figures, the foot wrapping bands 200 change in cross sectional shape from a relatively thin and flat shape at the rearwardly extending segment 202R and the forwardly extending segment 202F to relatively circular shape at the lace engaging element 202L. Transitional areas 202T include an area intermediate in cross sectional shape between: (a) the relatively thin and flat cross sectional shape of rearwardly extending segment 202R and forwardly extending segment 202F and (b) the relatively circular cross sectional shape at the lace engaging element 202L. One or more of the foot wrapping bands 200 may be formed as a unitary, one-piece construction, if desired. The relatively thin and flat shape of the forwardly extending segment 202F and the rearwardly extending segment 202R can help provide a more comfortable fit or feel, e.g., when a lace (e.g., 300) pulls the foot wrapping band(s) 200 tight, in some instances into contact with the wearer's foot. The thin and flat shape can help spread out the applied force and thus moderate the feel of the foot wrapping band(s) 200 against the wearer's foot.
As some more specific examples, at least one of the rearwardly extending band segments 202R and/or the forwardly extending medial band segments 202F has a longitudinal length L3, a width W3, and a thickness T3, wherein:
T3≥1 mm, W3≥3T3, and L3≥10W3.
In some examples, T3 will be greater than or equal to 2 mm and/or greater than or equal to 3 mm. As other options or alternatives, T3 may be less than 5 mm or even less than 4 mm and/or W3 may be at least 3 mm, at least 5 mm, at least 8 mm, or even at least 10 mm. As other additional or alternative example features, in the lace engaging element 202L area of the foot wrapping band(s) 200, the lace engaging element 202L may have a diameter D of less than 15 mm, and in some examples, a diameter of less than 12 mm, or even less than 10 mm. The transitional area(s) 202T may have a length dimension of less than 25 mm, and in some examples, less than 20 mm, less than 15 mm, or even less than 10 mm.
In at least some examples of this aspect of the invention, the rearwardly extending segment 202R and/or the forwardly extending segment 202F may be shaped somewhat like a “flat” shoelace, and optionally made of the same material(s) as conventional shoelaces, e.g., for athletic footwear. As some more specific examples, the foot wrapping bands 200 (or at least the rearwardly extending segment 202R and/or the forwardly extending segment 202F thereof) may be made from leather, cotton, jute, hemp, other materials used in the manufacture of rope, synthetic fibers (e.g., polyesters), etc. In at least some examples of this invention, the foot wrapping bands 200 (or at least the rearwardly extending segment 202R and/or the forwardly extending segment 202F thereof) may be made from relatively “unstretchable” materials (e.g., materials that stretch less than 10% of their axial length under a tensile force of 50 lbs).
FIGS. 4A-4G, along with FIGS. 1A-1C and 2A, illustrate one manner in which foot wrapping band(s) 200 may be engaged with a footwear upper 102 and/or a lace 300 in accordance with at least some examples of this invention. With particular reference to FIG. 4A, the upper shell 110 is illustrated with a set of foot wrapping bands 200 laid out on its interior surface. As shown in FIG. 4A, this example upper 102 (e.g., upper shell 110) includes a medial sidewall 110M and a lateral sidewall 110L, and a top panel 112 is engaged or integrally formed with at least one of the medial sidewall 110M and/or the lateral sidewall 110L. The medial sidewall 110M, the lateral sidewall 110L, and the top panel 112 define a lace engaging region 204 of the upper 102 and/or the upper shell 110, and this lace engaging region 204 has a medial side edge 204M, a lateral side edge 204L, and a forward edge 204F. This example upper 102 also may include a bottom plantar support surface 110S component (not shown in FIG. 4A) and/or a bootie component 120, e.g., of the types described above and/or having any of the structural features, connections, and/or other characteristics described above. The outer edge of the upper shell 110 shown in FIG. 4A may be engaged with a separate bottom plantar support surface 110S component (such as a footwear strobel member), e.g., as shown in FIG. 2A.
As further shown in FIG. 4A, the medial side edge 204M of the lace engaging region 204 of this illustrated example upper shell 110 includes one or more of a first medial side opening 210O, a second medial side opening 212O located forward of the first medial side opening 210O, a third medial side opening 214O located forward of the second medial side opening 212O, a fourth medial side opening 216O located forward of the third medial side opening 214O, a fifth medial side opening 218O located forward of the fourth medial side opening 216O, and a rearmost medial side opening 220O located rearward of the first medial side opening 210O. Similarly, the lateral side edge 204L of the lace engaging region 204 of this illustrated example upper shell 110 includes one or more of a first lateral side opening 230O, a second lateral side opening 232O located forward of the first lateral side opening 230O, a third lateral side opening 234O located forward of the second lateral side opening 232O, a fourth lateral side opening 236O located forward of the third lateral side opening 234O, a fifth lateral side opening 238O located forward of the fourth lateral side opening 236O, and a rearmost lateral side opening 240O located rearward of the first lateral side opening 230O. Note also FIGS. 4D and 4E. The upper shell 110 of this illustrated example further includes lace engaging slits or slots 222 located adjacent the side openings 210O-220O and 230O-240O. In this illustrated example, each side opening 210O-220O and 230O-240O has a lace engaging slit or slot 222 associated with it, but the side opening 210O-220O and 230O-240O is not continuous with its associated lace engaging slit or slot 222. In other words, in this illustrated example, a continuous portion 110V of the upper shell 110 extends between each side opening 210O-220O and 230O-240O and its associated lace engaging slit or slot 222.
The layout of foot wrapping bands of this example now will be described in more detail. Note, for example, FIGS. 2A and 4A. A first medial side foot wrapping band 250 includes: (a) a first medial lace engaging element (not shown in the view of FIG. 4A but akin to element 202L) extending through the first medial side opening 210O, (b) a first medial band segment 250R extending from the first medial lace engaging element and between the medial sidewall 110M and the bootie component 120, wherein the first medial band segment 250R is engaged with the bottom plantar support surface 110S of the upper shell 110 at a fixed bottom connection (e.g., sewn seam 130S) that is spaced inward from the outer perimeter edge 110P of the bottom plantar support surface 110S, and (c) a second medial band segment 250F extending from the first medial lace engaging element and between the medial sidewall 110M and the bootie component 120, wherein the second medial band segment 250F extends forward of the first medial band segment 250R and is engaged with the bottom plantar support surface 110S of the upper shell 110 at a fixed bottom connection (e.g., sewn seam 130S) that is spaced inward from the outer perimeter edge 110P of the plantar support surface 110S. In this manner, first medial band segment 250R and second medial band segment 250F form a “V” shaped structure that wraps around a medial side of the wearer's foot and may tighten against the foot when a lace 300 is tightened. The vertex of this “V” shaped structure forms the lace engaging element.
This example upper 102 structure further includes a second medial side foot wrapping band 252 that includes: (a) a second medial lace engaging element (not shown in the view of FIG. 4A but akin to element 202L) extending through the second medial side opening 212O, (b) a third medial band segment 252R extending from the second medial lace engaging element and between the medial sidewall 110M and the bootie component 120, wherein the third medial band segment 252R is engaged with the bottom plantar support surface 110S of the upper shell 110 at a fixed bottom connection (e.g., sewn seam 130S) that is spaced inward from the outer perimeter edge 110P of the bottom plantar support surface 110S, and (c) a fourth medial band segment 252F extending from the second medial lace engaging element and between the medial sidewall 110M and the bootie component 120, wherein the fourth medial band segment 252F extends forward of the third medial band segment 252R and is engaged with the bottom plantar support surface 110S of the upper shell 110 at a fixed bottom connection (e.g., sewn seam 130S) spaced inward from the outer perimeter edge 110P of the bottom plantar support surface 110S. In this manner, third medial band segment 252R and fourth medial band segment 252F form a “V” shaped structure (with the lace engaging element at the “V's” vertex) that wraps around a medial side of the wearer's foot and may tighten against the foot when a lace 300 is tightened. If desired, as shown in FIG. 4A, the medial side foot wrapping bands 250 and 252 may be arranged such that the third medial band segment 252R crosses the second medial band segment 250F along the medial sidewall 110M of the upper shell 110 (and along the medial side of a wearer's foot).
A third medial side foot wrapping band 254 is provided in this illustrated example structure that includes: (a) a third medial lace engaging element (not shown in the view of FIG. 4A but akin to element 202L) extending through the third medial side opening 214O, (b) a fifth medial band segment 254R extending from the third medial lace engaging element and between the medial sidewall 110M and the bootie component 120, wherein the fifth medial band segment 254R is engaged with the bottom plantar support surface 110S of the upper shell 110 at a fixed bottom connection (e.g., sewn seam 130S) that is spaced inward from the outer perimeter edge 110P of the bottom plantar support surface 110S, and (c) a sixth medial band segment 254F extending from the third medial lace engaging element and between the medial sidewall 110M and the bootie component 120, wherein the sixth medial band segment 254F extends forward of the fifth medial band segment 254R and is engaged with the bottom plantar support surface 110S of the upper shell 110 at a fixed bottom connection (e.g., sewn seam 130S) spaced inward from the outer perimeter edge 110P of the bottom plantar support surface 110S. In this manner, fifth medial band segment 254R and sixth medial band segment 254F form a “V” shaped structure (with the lace engaging element at the “V's” vertex) that wraps around a medial side of the wearer's foot and may tighten against the foot when a lace 300 is tightened. If desired, as shown in FIG. 4A, the medial side foot wrapping bands 252 and 254 may be arranged such that the fifth medial band segment 254R crosses the fourth medial band segment 252F along the medial sidewall 110M of the upper shell 110 (and along the medial side of a wearer's foot).
A fourth medial side foot wrapping band 256 provided in this illustrated example upper 102 structure includes: (a) a fourth medial lace engaging element (not shown in the view of FIG. 4A but akin to element 202L) extending through the fourth medial side opening 216O, (b) a seventh medial band segment 256R extending from the fourth medial lace engaging element and between the medial sidewall 110M and the bootie component 120, wherein the seventh medial band segment 256R is engaged with the bottom plantar support surface 110S of the upper shell 110 at a fixed bottom connection (e.g., sewn seam 130S) that is spaced inward from the outer perimeter edge 110P of the bottom plantar support surface 110S, and (c) an eighth medial band segment 256F extending from the fourth medial lace engaging element and between the medial sidewall 110M and the bootie component 120, wherein the eighth medial band segment 256F extends forward of the seventh medial band segment 256R and is engaged with the bottom plantar support surface 110S of the upper shell 110 at a fixed bottom connection (e.g., sewn seam 130S) spaced inward from the outer perimeter edge 110P of the bottom plantar support surface 110S. In this manner, seventh medial band segment 256R and eighth medial band segment 256F form a “V” shaped structure (with the lace engaging element at the “V's” vertex) that wraps around a medial side of the wearer's foot and may tighten against the foot when a lace 300 is tightened. If desired, as shown in FIG. 4A, the medial side foot wrapping bands 254 and 256 may be arranged such that the seventh medial band segment 256R crosses the sixth medial band segment 254F along the medial sidewall 110M of the upper shell 110 (and along the medial side of a wearer's foot).
This example upper 102 structure further includes a fifth medial side foot wrapping band 258 having: (a) a fifth medial lace engaging element (not shown in the view of FIG. 4A but akin to element 202L) extending through the fifth medial side opening 218O, (b) a ninth medial band segment 258R extending from the fifth medial lace engaging element and between the medial sidewall 110M and the bootie component 120, wherein the ninth medial band segment 258R is engaged with the bottom plantar support surface 110S of the upper shell 110 at a fixed bottom connection (e.g., sewn seam 130S) that is spaced inward from the outer perimeter edge 110P of the bottom plantar support surface 110S, and (c) a tenth medial band segment 258F extending from the fifth medial lace engaging element and between the medial sidewall 110M and the bootie component 120, wherein the tenth medial band segment 258F extends forward of the ninth medial band segment 258R and is engaged with the bottom plantar support surface 110S of the upper shell 110 at a fixed bottom connection (e.g., sewn seam 130S) spaced inward from the outer perimeter edge 110P of the bottom plantar support surface 110S.

If desired, as shown in FIG. 4A, the medial side foot wrapping bands 256 and 258 may be arranged such that the ninth medial band segment 258R crosses the eighth medial band segment 256F along the medial sidewall 110M of the upper shell 110 (and along the medial side of a wearer's foot).
The medial side of the upper 102 of this specifically illustrated example further includes a rearmost medial side foot wrapping band 260 that includes: (a) a medial lace engaging element (not shown in the view of FIG. 4A but akin to element 202L) extending through the rearmost medial side opening 220O; (b) a rearward extending medial band segment 260R extending from the medial lace engaging element and between the medial sidewall 110M and the bootie component 120, wherein the rearward extending medial band segment 260R is engaged with (i) a rear heel area of the bootie component 120 (see also FIG. 4F) and/or (ii) the bottom plantar support surface 110S of the upper shell 110 at a fixed bottom connection (e.g., sewn seam 130S) that is spaced inward from the outer perimeter edge 110P of the bottom plantar support surface 110S; and (c) another medial band segment 260F extending from the medial lace engaging element and between the medial sidewall 110M and the bootie component 120, wherein this other medial band segment 260F extends forward of the rearward extending medial band segment 260R and is engaged with the bottom plantar support surface 110S of the upper shell 110 at a fixed bottom connection (e.g., sewn seam 130S) spaced inward from the outer perimeter edge 110P of the bottom plantar support surface 110S and may tighten against the foot when a lace 300 is tightened. In this manner, the medial band segments 260R and 260F form a “V” shaped structure (with the lace engaging element at the “V's” vertex) that wraps around a medial side of the wearer's foot. If desired, as shown in FIG. 4A, the first medial side foot wrapping band 250 and the rearmost foot wrapping band 260 may be arranged such that the first medial band segment 250R crosses the medial band segment 260F along the medial sidewall 110M of the upper shell 110 (and along the medial side of a wearer's foot).
The layout of the foot wrapping bands on the lateral side of this example upper 102 now will be described in more detail. A first lateral side foot wrapping band 270 includes: (a) a first lateral lace engaging element (not shown in the view of FIG. 4A but akin to element 202L) extending through the first lateral side opening 230O, (b) a first lateral band segment 270R extending from the first lateral lace engaging element and between the lateral sidewall 110L and the bootie component 120, wherein the first lateral band segment 270R is engaged with the bottom plantar support surface 110S of the upper shell 110 at a fixed bottom connection (e.g., sewn seam 130S) that is spaced inward from the outer perimeter edge 110P of the bottom plantar support surface 110S, and (c) a second lateral band segment 270F extending from the first lateral lace engaging element and between the lateral sidewall 110L and the bootie component 120, wherein the second lateral band segment 270F extends forward of the first lateral band segment 270R and is engaged with the bottom plantar support surface 110S of the upper shell 110 at a fixed bottom connection (e.g., sewn seam 130S) that is spaced inward from the outer perimeter edge 110P of the plantar support surface 110S. In this manner, first lateral band segment 270R and second lateral band segment 270F form a “V” shaped structure that wraps around a lateral side of the wearer's foot and may tighten against the foot when a lace 300 is tightened. The lace engaging element is provided at the vertex of this “V” shaped structure.
This example upper 102 structure further includes a second lateral side foot wrapping band 272 that includes: (a) a second lateral lace engaging element (not shown in the view of FIG. 4A but akin to element 202L) extending through the second lateral side opening 232O, (b) a third lateral band segment 272R extending from the second lateral lace engaging element and between the lateral sidewall 110L and the bootie component 120, wherein the third lateral band segment 272R is engaged with the bottom plantar support surface 110S of the upper shell 110 at a fixed bottom connection (e.g., sewn seam 130S) that is spaced inward from the outer perimeter edge 110P of the bottom plantar support surface 110S, and (c) a fourth lateral band segment 272F extending from the second lateral lace engaging element and between the lateral sidewall 110L and the bootie component 120, wherein the fourth lateral band segment 272F extends forward of the third lateral band segment 272R and is engaged with the bottom plantar support surface 110S of the upper shell 110 at a fixed bottom connection (e.g., sewn seam 130S) spaced inward from the outer perimeter edge 110P of the bottom plantar support surface 110S. In this manner, third lateral band segment 272R and fourth lateral band segment 272F form a “V” shaped structure (with the lace engaging element at the “V's” vertex) that wraps around a lateral side of the wearer's foot and may tighten against the foot when a lace 300 is tightened. If desired, as shown in FIG. 4A, the lateral side foot wrapping bands 270 and 272 may be arranged such that the third lateral band segment 272R crosses the second lateral band segment 270F along the lateral sidewall 110L of the upper shell 110 (and along the lateral side of a wearer's foot).
A third lateral side foot wrapping band 274 is provided in this illustrated example structure that includes: (a) a third lateral lace engaging element (not shown in the view of FIG. 4A but akin to element 202L) extending through the third lateral side opening 234O, (b) a fifth lateral band segment 274R extending from the third lateral lace engaging element and between the lateral sidewall 110L and the bootie component 120, wherein the fifth lateral band segment 274R is engaged with the bottom plantar support surface 110S of the upper shell 110 at a fixed bottom connection (e.g., sewn seam 130S) that is spaced inward from the outer perimeter edge 110P of the bottom plantar support surface 110S, and (c) a sixth lateral band segment 274F extending from the third lateral lace engaging element and between the lateral sidewall 110L and the bootie component 120, wherein the sixth lateral band segment 274F extends forward of the fifth lateral band segment 274R and is engaged with the bottom plantar support surface 110S of the upper shell 110 at a fixed bottom connection (e.g., sewn seam 130S) spaced inward from the outer perimeter edge 110P of the bottom plantar support surface 110S. In this manner, fifth lateral band segment 274R and sixth lateral band segment 274F form a “V” shaped structure (with the lace engaging element at the “V's” vertex) that wraps around a lateral side of the wearer's foot and may tighten against the foot when a lace 300 is tightened. If desired, as shown in FIG. 4A, the lateral side foot wrapping bands 272 and 274 may be arranged such that the fifth lateral band segment 274R crosses the fourth lateral band segment 272F along the lateral sidewall 110L of the upper shell 110 (and along the lateral side of a wearer's foot).
A fourth lateral side foot wrapping band 276 provided in this illustrated example upper 102 structure includes: (a) a fourth lateral lace engaging element (not shown in the view of FIG. 4A but akin to element 202L) extending through the fourth lateral side opening 236O, (b) a seventh lateral band segment 276R extending from the fourth lateral lace engaging element and between the lateral sidewall 110L and the bootie component 120, wherein the seventh lateral band segment 276R is engaged with the bottom plantar support surface 110S of the upper shell 110 at a fixed bottom connection (e.g., sewn seam 130S) that is spaced inward from the outer perimeter edge 110P of the bottom plantar support surface 110S, and (c) an eighth lateral band segment 276F extending from the fourth lateral lace engaging element and between the lateral sidewall 110L and the bootie component 120, wherein the eighth lateral band segment 276F extends forward of the seventh lateral band segment 276R and is engaged with the bottom plantar support surface 110S of the upper shell 110 at a fixed bottom connection (e.g., sewn seam 130S) spaced inward from the outer perimeter edge 110P of the bottom plantar support surface 110S. In this manner, seventh lateral band segment 276R and eighth lateral band segment 276F form a “V” shaped structure (with the lace engaging element at the “V's” vertex) that wraps around a lateral side of the wearer's foot and may tighten against the foot when a lace 300 is tightened. If desired, as shown in FIG. 4A, the lateral side foot wrapping bands 274 and 276 may be arranged such that the seventh lateral band segment 276R crosses the sixth lateral band segment 274F along the lateral sidewall 110L of the upper shell 110 (and along the lateral side of a wearer's foot).
This example upper 102 structure further includes a fifth lateral side foot wrapping band 278 having: (a) a fifth lateral lace engaging element (not shown in the view of FIG. 4A but akin to element 202L) extending through the fifth lateral side opening 238O, (b) a ninth lateral band segment 278R extending from the fifth lateral lace engaging element and between the lateral sidewall 110L and the bootie component 120, wherein the ninth lateral band segment 278R is engaged with the bottom plantar support surface 110S of the upper shell 110 at a fixed bottom connection (e.g., sewn seam 130S) that is spaced inward from the outer perimeter edge 110P of the bottom plantar support surface 110S, and (c) a tenth lateral band segment 278F extending from the fifth lateral lace engaging element and between the lateral sidewall 110L and the bootie component 120, wherein the tenth lateral band segment 278F extends forward of the ninth lateral band segment 278R and is engaged with the bottom plantar support surface 110S of the upper shell 110 at a fixed bottom connection (e.g., sewn seam 130S) spaced inward from the outer perimeter edge 110P of the bottom plantar support surface 110S. In this manner, ninth lateral band segment 278R and tenth lateral band segment 278F form a “V” shaped structure (with the lace engaging element at the “V's” vertex) that wraps around a lateral side of the wearer's foot and may tighten against the foot when a lace 300 is tightened. If desired, as shown in FIG. 4A, the lateral side foot wrapping bands 276 and 278 may be arranged such that the ninth lateral band segment 278R crosses the eighth lateral band segment 276F along the lateral sidewall 110L of the upper shell 110 (and along the lateral side of a wearer's foot).
The lateral side of the upper 102 of this specifically illustrated example further includes a rearmost lateral side foot wrapping band 280 that includes: (a) a lateral lace engaging element (not shown in the view of FIG. 4A but akin to element 202L) extending through the rearmost lateral side opening 240O; (b) a rearward extending lateral band segment 280R extending from the lateral lace engaging element and between the lateral sidewall 110L and the bootie component 120, wherein the rearward extending lateral band segment 280R is engaged with (i) a rear heel area of the bootie component 120 (see also FIG. 4F) and/or (ii) the bottom plantar support surface 110S of the upper shell 110 at a fixed bottom connection (e.g., sewn seam 130S) that is spaced inward from the outer perimeter edge 110P of the bottom plantar support surface 110S; and (c) another lateral band segment 280F extending from the lateral lace engaging element and between the lateral sidewall 110L and the bootie component 120, wherein this other lateral band segment 280F extends forward of the rearward extending lateral band segment 280R and is engaged with the bottom plantar support surface 110S of the upper shell 110 at a fixed bottom connection (e.g., sewn seam 130S) spaced inward from the outer perimeter edge 110P of the bottom plantar support surface 110S. In this manner, the lateral band segments 280R and 280F form a “V” shaped structure (with the lace engaging element at the “V's” vertex) that wraps around a lateral side of the wearer's foot and may tighten against the foot when a lace 300 is tightened. If desired, as shown in FIG. 4A, the first lateral side foot wrapping band 270 and the rearmost foot wrapping band 280 may be arranged such that the first lateral band segment 270R crosses the lateral band segment 280F along the lateral sidewall 110L of the upper shell 110 (and along the lateral side of a wearer's foot).
As further shown in FIGS. 1A-1C, 4B, 4C, 4E, and 4F, the lace engaging elements 202L of the various foot wrapping bands (e.g., 200, 250, 252, 254, 256, 258, 260, 270, 272, 274, 276, 278, and 280) engage a shoelace 300. Pulling on the shoelace 300 tightens the foot wrapping bands (e.g., one or more of 200, 250, 252, 254, 256, 258, 260, 270, 272, 274, 276, 278, and 280) around the wearer's foot. Tightening the lace 300, together with the various features described above (e.g.: (a) the “V” shapes formed by the foot wrapping band segments, (b) the “overlapping” or “intersecting” nature of the foot wrapping band segments along the side of the wearer's foot, (c) the fixing location for the foot wrapping band segments and/or the bootie component 120 with the upper shell 110 inward from the outer perimeter edge 110P of the plantar support surface 110S (and beneath/beyond the bight line where the upper shell 110 meets the bootie component 120), and/or (d) the form fitting sock-like bootie component 120), work together to provide a secure and “locked down” feel of the upper 102 on the wearer's foot.
As noted above, in at least some examples of this invention, the upper shell 110 may include lace engaging slits or slots 222 located adjacent the side openings 210O-220O and 230O-240O through which the lace engaging element 202L of the foot wrapping bands bands (e.g., 200, 250, 252, 254, 256, 258, 260, 270, 272, 274, 276, 278, and 280) extend. FIGS. 4B-4E provide close up views of at least some of the side openings 210O-220O and 230O-240O through which the lace engaging element 202L of the foot wrapping bands (e.g., 200, 250, 252, 254, 256, 258, 260, 270, 272, 274, 276, 278, and 280) extend and the lace engaging slit or slot 222 through which the lace 300 extends. As shown, in these illustrated examples, the side opening(s) 210O-220O and 230O-240O are not continuous with its associated lace engaging slit or slot 222. In other words, in this illustrated example, a continuous portion 110V of the upper shell 110 extends between each side opening 210O-220O and 230O-240O and its associated lace engaging slit or slot 222. In this example upper 102, lace 300 passes through both slits/slots 222 of the upper shell 110 and the lace engaging elements 202L of the foot wrapping bands 250, 252, 254, 256, 258, 260, 270, 272, 274, 276, 278, and 280. The slits/slots 222 are located closer to their respective lateral edge 204L and medial edge 204M of the lace engaging region 204 of the upper shell 110 than are the respective side openings 210O-220O and 230O-240O (e.g., the openings 210O-220O and 230O-240O are located closer to a bottom edge of the upper shell 110 than are their respective slits/slots 222).
If desired, as best shown perhaps in FIG. 4D, the edges of the side opening(s) 210O-220O and/or 230O-240O and/or lace engaging slits or slots 222 formed in the upper shell 110 may include a reinforcing structure 110R, e.g., to prevent undesired tearing of the upper 102 and/or upper shell 110 material when the lace 300 is tightened or the upper 102 is otherwise stressed. This reinforcement 110R may constitute a coating or other wear resistant and/or tear resistant material, e.g., applied around the opening(s) and/or slit(s), such as a TPU or other tear resistant polymeric material. In use, the lace 300 extends through the slits/slots 222 and through the lace engaging element 202L extending through the side openings 210O-220O and 230O-240O and may be used to tighten the footwear 100 to the wearer's foot while reinforcements 110R prevent tearing of the upper shell 110, e.g., when the lace 300 is tightened.
FIGS. 4B-4D further illustrate that the lace engaging slits or slots 222 in this illustrated example are generally oriented transverse to its respective lace engaging edge of the upper shell 110 (e.g., transverse to the medial side edge 204M or the lateral side edge 204L of the lace engaging region 204) and/or generally parallel to the forward edge 204F of the lace engaging region 204. Also, as shown in these figures, the slits/slots 222 generally extend in a side-to-side and/or top-to-bottom direction of the upper 102 (and not in a heel-to-toe direction). In this manner, the lace 300 can move upward and/or downward and/or sideways in the slit or slot 222 as the lace 300 is tightened. These features can help assure that the lace 300 better engages and pulls the lace engaging elements 202L of the foot wrapping bands (e.g., 200, 250, 252, 254, 256, 258, 260, 270, 272, 274, 276, 278, and/or 280), thereby better tightening the foot wrapping bands around the wearer's foot (providing better support, a better “locked down” feel, etc.).
FIG. 4G shows another example upper shell 410 with foot wrapping bands (250, 252, 254, 256, 258, 260, 270, 272, 274, 276, 278, and/or 280) associated with it similar to the structure shown in FIG. 4A. When the same reference numbers are used in FIG. 4G as used in the other figures described above, the same or a similar part is intended, and a more detailed description of the same or similar parts may be omitted. In the upper shell 410 of FIG. 4G, however, the side openings 210O-220O and 230O-240O are omitted as compared to the upper shell 110 shown in FIG. 4A. Rather, the lace engaging element(s) 202L of the foot wrapping band(s) 250, 252, 254, 256, 258, 260, 270, 272, 274, 276, 278, and/or 280 extend through the slits/slots 222, and the lace 300 can directly engage the lace engaging element(s) 202L of the foot wrapping band(s) 250, 252, 254, 256, 258, 260, 270, 272, 274, 276, 278, and/or 280 without directly extending through the slits/slots 222 (i.e., in this upper shell 410, the lace 300 does not extend through slits/slots 222). The foot wrapping band(s) 250, 252, 254, 256, 258, 260, 270, 272, 274, 276, 278, and/or 280 can move upward and/or downward and/or sideways in the slit/slot 222 as the lace 300 is tightened. These features can help assure that the lace 300 better engages and pulls the lace engaging elements 202L of the foot wrapping bands (e.g., 200, 250, 252, 254, 256, 258, 260, 270, 272, 274, 276, 278, and/or 280), thereby better tightening the foot wrapping bands around the wearer's foot (providing better support, a better “locked down” feel, etc.).
