Patent Application
20220079293
This disclosure relates generally to articles of footwear and more particularly to lace-receiving structures for articles of footwear.
An article of footwear (also referred to herein as “the article” or “the footwear”) typically includes two main components: a sole structure and an upper. The sole structure is configured for supporting the wearer's foot and providing cushioning between the wearer's foot and the ground. The upper is coupled to the sole structure and is configured for securing the wearer's foot to the sole structure.
The article of footwear can also include a closure system. In some examples, a closure system may include one or more guides (also referred to herein as “receiving structures”) configured to receive an adjustment member (e.g., a lace, cord, strap, etc.). The adjustment member can be released and/or loosened to allow the wearer to insert their foot into or remove their foot from the article of footwear. The adjustment member can also be tightened and/or fastened to secure the wearer's foot within the article of footwear.
Aspects and advantages of the disclosed technology will be set forth in part in the following description, or may be obvious from the description, or may be learned through practice of the technology disclosed in the description.
Disclosed herein are lace-receiving members for articles of footwear that can provide, for example, additional support for lateral movements. Specifically, because the lace-receiving members may extend over the upper and/or because they may be constructed from a stiffer material than the rest of the upper, the lace-receiving members may provide additional support to the upper in areas of the footwear that experience higher stress during lateral movements. As such, the lace-receiving members may limit and/or reduce movement of a wearer's foot relative to the sole structure of the footwear and thus may enhance the wearer's ability to perform quick, explosive lateral movements. That is, the lace-receiving members may hold the wearer's foot more securely in place during lateral movements.
Additionally or alternatively, the disclosed lace-receiving members can, for example, provide an aesthetic element (e.g., design, color, texture, profile, geometry, surface feature, etc.) that can be changed relatively easily (e.g., by a manufacturer, a seller, and/or an end user). In some instances, the lace-receiving members can be fixedly attached to an article of footwear. In other embodiments, the lace-receiving member can be removably coupled to an article of footwear.
In some embodiments, an article of footwear comprises a sole structure, an upper, and a lace-receiving structure. The upper is coupled to the sole structure and forms a foot-receiving cavity therebetween. The upper comprises an aperture configured to receive the lace-receiving structure. The lace-receiving structure extends through the aperture in the upper, underneath the upper, and towards the sole structure.
In other embodiments, an article of footwear comprises a sole structure, an upper, and a lace-receiving structure. The upper is coupled to the sole structure and forms a foot-receiving cavity therebetween. The lace-receiving structure is coupled to the upper and comprises an anchor portion and a main body portion. The anchor portion extends into the foot-receiving cavity underneath the upper. The main body portion extends above the upper, over an exterior surface of the upper.
In yet further embodiments, an article of footwear comprises a sole structure, an upper, a lace-receiving structure, and a reinforcing element. The upper is coupled to the sole structure and forms a foot-receiving cavity therebetween. The upper comprises an aperture configured to receive the lace-receiving structure. The lace-receiving structure extends through the aperture into the foot-receiving cavity and is coupled to the reinforcing element. The reinforcing element is coupled to the upper.
These and other features, aspects, and/or advantages of the present disclosure will become better understood with reference to the following description and the claims. The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments of the disclosed technology and, together with the description, explain the principles of the disclosure.

As an example, the lace-receiving structure may include an aperture (e.g., eyelet), channel, and/or groove through which the adjustment member is configured to extend. When included in an article of footwear, the lace-receiving structure is configured to adjustably couple the adjustment member to the article of footwear.
As used herein, the terms “articles of footwear,” “articles,” and/or “footwear” mean any type of footwear, including, for example, casual shoes, walking shoes, sneakers, tennis shoes, running shoes, soccer shoes, football shoes, rugby shoes, basketball shoes, baseball shoes, boots, sandals, etc.
Although the figures may illustrate an article of footwear intended for use on only one foot (e.g., a right foot) of a wearer, one skilled in the art and having the benefit of this disclosure will recognize that a corresponding article of footwear for the other foot (e.g., a left foot) would be a mirror image of the right article of footwear.
Unless explained otherwise, all technical and scientific terms used herein have the same meaning as commonly understood to one of ordinary skill in the art to which this disclosure belongs. Although methods and materials similar or equivalent to those described herein can be used in the practice or testing of the present disclosure, suitable methods and materials are described below. The materials, methods, and examples are illustrative only and not intended to be limiting. Other features of the disclosure are apparent from the detailed description, abstract, and drawings.
The Disclosed Technology and Exemplary Embodiments
A lace-receiving structure is configured to receive and an adjustment member (e.g., a lace, string, cable, cord, wire, band, strap, etc.) and may be included in an article of footwear. The lace-receiving structure typically includes an eyelet that is configured to receive the adjustment member and a support structure that is configured to couple the eyelet to the article of footwear. In some examples, the lace-receiving structure may be included in an article of footwear. In such examples, the article of footwear typically includes a sole structure and an upper in addition to the lace-receiving structure. The sole structure is configured for supporting the wearer's foot and providing cushioning between the wearer's foot and the ground. The upper is coupled to the sole structure and forms a foot-receiving cavity. The upper is configured for securing the wearer's foot to the sole structure and/or can protect the wearer's foot.
For example,
Referring now to
Eyelet 12 may comprise a loop 20 that defines an aperture 22 (which may also be referred to herein as “channel” and/or “opening”), which can receive an adjustment member. The loop 20 itself can be constructed from, formed of, and/or comprise various materials. For example, the loop 20 can be constructed from, formed of, and/or comprise one or more of textiles, foam, leather, synthetic leather, and/or polymers (e.g., rubber and/or plastic). The aperture 22 may extend through the loop 20, from a first side 24 of the loop 20 to a second side 26 of the loop 20 that is opposite the first side 24. The aperture 22 can be one or more of a void, empty space, and/or hollow region that is configured to receive the adjustment member.
The loop 20 may be coupled to the support structure 14. Specifically, the loop 20 may be coupled to the main body portion 16 of the support structure 14. In some embodiments, the loop 20 may be directly coupled to the main body portion 16. In some such embodiments, the loop 20 and the main body portion 16 may be formed as a single, unitary component (e.g., by knitting or molding). In other such embodiments, the loop 20 and the main body portion 16 may be formed separately as two discrete components and may then be coupled directly to one another (e.g., by stitching, adhesive, fasteners, etc.) In other embodiments, the loop 20 may be coupled to the main body portion 16 via one or more intermediate components.
In some embodiments, the loop 20 may be coupled to a first side 28 (which may also be referred to as an “inner side 28” and/or a “shoe-facing side 28” since it may be configured to face the article of footwear when included in and/or coupled to the article of footwear) of the main body portion 16 of the support structure 14 that is opposite a second side 30 of the main body portion 16 (which may also be referred to as an “outer side 30” and/or an “exterior-facing side 30”). In some embodiments, the loop 20 may be coupled farther from a proximal end 32 of the main body portion 16 than a distal end 34 of the main body portion 16. That is, the loop 20 may be positioned more proximate the distal end 34 than the proximal end 32. In some such embodiments, the loop 20 may nonetheless be spaced inwardly away from the distal end 34 by a distance “D.” In some further such embodiments, the loop 20 may be spaced away from the distal end 34 by at least 1/10, at least 1/9, at least ⅛, at least 1/7, at least ⅙, at least ⅕, at least ¼, at least ⅓, at most ½, at most ⅓, and/or at most ¼ of the length of the main body portion 16, where the length of the main body portion 16 is the distance between the proximal end 32 and the distal end 34 of the main body portion 16.
In some such embodiments, the loop 20 may be coupled to the main body portion 16 at a position on the main body portion 16 that is at least 1/10, at least 1/9, at least ⅛, at least 1/7, at least ⅙, at least ⅕, at least ¼, at least ⅓, at most ½, at most ⅓, and/or at most ¼ of the length of the main body portion 16 away from the distal end 34 of the main body portion 16. That is, the attachment point between the main body portion 16 and the loop 20 (the location on the main body portion 16 where the loop 20 is attached to the main body portion 16) may be located at least 1/10, at least 1/9, at least ⅛, at least 1/7, at least ⅙, at least ⅕, at least ¼, at least ⅓, at most ½, at most ⅓, and/or at most ¼ of the length of the main body portion 16 away from the distal end 34 of the main body portion 16.
In some embodiments, the distance between the loop 20 and the distal end 34 is fixed and does not change. For example, the loop 20 may be rigid (i.e., may not bend) and/or the loop 20 may be rigidly coupled to the main body portion 16 such that the loop 20 is not configured to bend, rotate, and/or otherwise move relative to the main body portion 16.
However, in other embodiments, the distance between the loop 20 and the distal end 34 is variable. For example, the loop 20 may be configured to bend and/or otherwise move relative to main body portion 16. For example, the loop 20 may be configured to bend towards, pivot towards, compress, deform, and/or flatten against the main body portion 16 (e.g., the distal end 34) when the adjustment members of the article of footwear are tightened and the lace-receiving structure 10 is compressed against the upper of the article of footwear. In particular, the loop 20 may be configured to move between a more extended first position and a flatter second position. In the extended first position, the loop 20 may extend farther away from the main body portion 16 than in the flatter second position.
In some embodiments, the loop 20 itself may be configured to bend and/or deform when a wearer pulls on and/or otherwise tightens the adjustment members (i.e., when a lace-tightening force is applied by a wearer). In one such embodiment, the loop 20 may comprise a flexible material (e.g., fabric) that is configured to bend and/or deform under a compressive force. In another embodiment, the loop 20 may be pivotably coupled to the main body portion 16 and may be configured to pivot relative to the main body portion 16 (e.g., towards the distal end 34).
In embodiments where the loop 20 is configured to move relative to the main body portion 16 (i.e., where the distance between the loop 20 and the distal end 34 is variable), the loop 20 may still be configured to be spaced inwardly away from the distal end 34 by at least 1/20, at least 1/18, at least 1/16, at least 1/14, at least 1/12, at least 1/10, at least 1/9, at least ⅛, at least 1/7, at least ⅙, at least ⅕, at least ¼, at least ⅓, at most ½, at most ⅓, and/or at most ¼ of the length of the main body portion 16 even at its closest approach to the distal end 34 (such as when the loop 20 is in the flatter second position). In other embodiments, the loop 20 may be spaced inwardly away from the distal end 34 in the more extended first position (e.g., when a lace-tightening force is not applied), but may be located at, aligned with, and/or may extend past the distal end 34 of the main body portion in the flatter second position (e.g., when a the lace-tightening force is applied). In yet further embodiments, the loop 20 may not be spaced inwardly away from the distal end 34 of the main body portion 16, and may be located at, aligned with, and/or may extend past the distal end 34 of the main body portion 16 in both the more extended first position and the flatter second position.
The main body portion 16 may be coupled to the anchor portion 18 at its proximal end 32. In some embodiments, the proximal end 32 may be directly coupled to the anchor portion 18. In some such embodiments, the main body portion and the anchor portion 18 may be formed as a single, unitary component (e.g., by knitting or molding). In other such embodiments, the main body portion and the anchor portion 18 may be formed as two discrete components and thereafter may be coupled directly to one another (e.g., by stitching, adhesive, fasteners, etc.) In other embodiments, the proximal end 32 of the main body portion 16 may be coupled to the anchor portion 18 via one or more intermediate components.
The main body portion 16 and/or the anchor portion 18 may be constructed from, formed of, and/or comprise various materials. For example, the main body portion 16 and/or the anchor portion 18 can be constructed from, formed of, and/or comprise one or more of textiles, foam, leather, synthetic leather, natural polymers and/or synthetic polymers (e.g., synthetic rubber). In some embodiments, the anchor portion 18 and the main body portion 16 may be formed from the same materials. In other embodiments, the anchor portion 18 and the main body portion 16 may be formed from different materials.
As noted above, the inner side 28 of the main body portion 16 may be configured to face the upper of an article of footwear when the lace-receiving structure 10 is included in and/or coupled to the article of footwear. In one embodiment, the inner side 28 of the main body portion 16 may be configured to directly contact at least a portion of the upper (such as when a wearer tightens the adjustment members). The outer side 30 is opposite the inner side 28 and may be configured to face away from the upper of the article of footwear when included in and/or coupled to the article of footwear. The distance between the outer side 30 and the inner side 28 defines the thickness of the main body portion 16. The main body portion 16 also may include a third side 36 (which may also be referred to herein as “first edge 36”) and a fourth side 38 (which may also be referred to herein as “second edge 38”) that is opposite the third side 36. The third side 36 and fourth side 38 may define and/or be the anterior and/or posterior sides of the main body portion 16. The distance between the third side 36 and the fourth side 38 may define the width of the main body portion 16.
The main body portion 16 may be longer than it is wide and/or thick. That is, the length of the main body portion 16 (the distance between the proximal end 32 and the distal end 34) may be the largest dimension of the main body portion 16. For example, the length of the main body portion 16 may be at least one and a half times, at least two times, at least three times, at least four times, at most ten times, at most eight times, and/or at most six times greater than the width of the main body portion 16. In some embodiments, the main body portion 16 may be wider than it is thick. That is width of the main body portion 16 (the distance between the third side 36 and the fourth side 38 of the main body portion 16) may be greater than the thickness of the main body portion (the distance between the inner side 28 and the outer side 30). For example, the width of the main body portion 16 may be at least two times, at least four times, at least 6 times, at least 8 times, at least 10 times, at least 15 times, at least 20 times, at most one hundred times, at most eighty times, and/or at most sixty times, the thickness of the main body portion 16. In some embodiment, the width and/or thickness of the main body portion 16 may be uniform. However, in other embodiments, and as will be discussed in greater detail below with reference to
Thus, although depicted schematically as a rectangular prism in
Anchor portion 18 (which may also be referred to herein as “flange 18”) may be configured to couple the lace-receiving structure 10 to the article of footwear. Anchor portion 18 may extend from the proximal end 32 of the main body portion 16 at an angle relative to the main body portion 16. In one embodiment, the anchor portion 18 may extend substantially orthogonally relative to the proximal end 32 of the main body portion 16. However, in other examples, the anchor portion 18 may extend away from the proximal end 32 of the main body portion 16 at an angle of at least 20 degrees, at least 30 degrees, at least 50 degrees, at least 60 degrees, at least 70 degrees, at least 80 degrees, at least 90 degrees, at most 160 degrees, at most 150 degrees, at most 140 degrees, at most 130 degrees, at most 120 degrees, at most 110 degrees, at most 100 degrees, and/or at most 90 degrees.
Anchor portion 18 may include a first side 42 (which may also be referred to herein as “the upper side 42” and/or the “upper-facing side 42” since it may be configured to face and/or directly contact an inner surface of the upper when included in the article of footwear) and a second side 44 (which may also be referred to herein as “the lower side 44” and/or the “foot-facing side 44 since it may be configured to face and/or directly contact a wearer's foot when included in the article of footwear) opposite the first side 42. The distance between the first side 42 and the second side 44 may define the thickness of the anchor portion 18. The anchor portion 18 may also include a first end 46, a second end 48 opposite the first end 46, a first edge 50, and a second edge 52 opposite the first edge 50. The distance between the first end 46 and the second end 48 may define the length of the anchor portion 18, and the distance between the first edge 50 and the second edge 52 may define the width of the anchor portion 18.
Although the anchor portion 18 is illustrated as having a generally rectangular profile when viewed from above (looking down at the first side 42) or below (looking up at second side 44) in
In some embodiments the anchor portion 18 may be longer and/or wider than it is thick. That is, the length (the distance between the first end 46 and the second end 48) and width (the distance between the first edge 50 and the second edge 52) of the anchor portion 18 may be greater than the thickness (the distance between the first side 42 and the second side 44) of the anchor portion 18. For example, the length and/or width of the anchor portion 18 may be at least one and a half times, at least two times, at least three times, at least four times, at least six times, at least eight times, at least ten times, at most forty times, at most thirty times, and/or at most twenty times greater than the thickness of the anchor portion 18. In some embodiments, the width and/or thickness of the anchor portion 18 may be uniform. However, in other embodiments, and as will be discussed in greater detail below with reference to
Thus, although depicted schematically as a rectangular prism in
In some embodiments, main body portion 16 may be directly coupled to and/or may extend from the first side 42 of the anchor portion 18. In some such embodiments, the proximal end 32 of the main body portion 16 may be directly coupled to the first side 42 of the anchor portion 18. In some embodiments (such as those illustrated in
In other embodiments, main body portion 16 may be directly coupled to and/or may extend from the first end 46 and/or the second end 48. In some such embodiments, the first side 28 and/or the second side 30 of the main body portion 16 may be directly coupled to the first end 46 and/or the second end 48 of the anchor portion 18. In some such embodiments, the proximal end 32 of the main body portion 16 may be substantially flush and/or aligned with the second side 44 of the anchor portion 18. In other such embodiments, the proximal end 32 of the main body portion 16 may extend past the second side 44 of the anchor portion 18.
The lace-receiving structure 10 may be stiffest (i.e., may have a higher Young's modulus) at and/or near where the main body portion 16 and the anchor portion 18 meet and/or are coupled to one another. As one example, the lace-receiving structure 10 may be thickest where the main body portion 16 and the anchor portion 18 meet. Additionally or alternatively, the lace-receiving structure 10 may be constructed from a different, stiffer material at and/or near where the main body portion 16 and the anchor portion 18 meet and/or are coupled to one another than at more distal ends of the main body portion 16 and/or anchor portion 18. In this way, the lace-receiving structure 10 may be configured to bend and/or deform more easily more proximate the distal ends of the main body portion 16 and/or the anchor portion 18 and may be configured to be more rigid nearer where the main body portion 16 and anchor portion 18 meet. Such a configuration may permit the main body portion 16 and/or anchor portion 18 to each individually bend, but may restrict bending of the main body portion 16 and anchor portion 18 relative to one another where the meet and/or are coupled to one another.
In particular,
In some embodiments, the main body portion 16 may be longer than the anchor portion (e.g., anchor portion 18, anchor portion 100, anchor portion 200, anchor portion 300, anchor portion 400, etc.). For example, the length of the main body portion 16 (distance between the proximal end 32 and the distal end 34) may be greater than the length of the anchor portion (e.g., distance between the first end 46 and the second end 48) by at least one and a half, at least two, at least three, at least four, at least five, at least six, at least eight, at least ten, at least twelve, at most eighty, at most sixty, at most forty, at most twenty, at most fifteen, times the length of the anchor portion 18. In some embodiments, the main body portion 16 may be thicker than the anchor portion. For example, the average thickness of the main body portion 16 may be at least one and a half, at least two, at least three, at least four, at most twenty, at most fifteen, and/or at most ten times the average thickness of the anchor portion.
In the embodiment of
Main body portion 816 and anchor portion 818 of lace-receiving structure 800 may form a corner 802 where they meet (e.g., where the proximal end 832 of the main body portion 816 and the first end 846 of the anchor portion 818 meet). The lace-receiving structure 800 may be stiffer at the corner 802 than a distal end 834 of the main body portion 816 and/or the distal ends of the anchor portion 818 (e.g., the second end 848 of the anchor portion 818 in examples where the main body portion 816 is coupled to the anchor portion 818 at the first end 846). Thus, the lace-receiving structure 800 may be stiffer at the proximal end 832 of the main body portion 816 than at the distal end 834 of the main body portion 816, and/or may be stiffer at the first end 846 of the anchor portion 818 than at the second end 848 of the anchor portion 818 (in examples where the main body portion 816 is coupled to the anchor portion 818 at the first end 846 of the anchor portion 818). In some examples, the stiffness of the lace-receiving structure 800 may monotonically decrease when progressing away from the corner 802 towards the distal end 834 of the main body portion 816 and/or the distal ends of the anchor portion 818, and vice versa (the stiffness of the lace-receiving structure 800 may monotonically increase when progressing towards the corner 802 away from the distal ends of the anchor portion 818 and/or the distal end 834 of the main body portion 816).
In some embodiments, the lace-receiving structure 800 may be stiffer at the corner 802 by virtue of being thicker at the corner 802. For example, as illustrated in
Additionally or alternatively, the lace-receiving structure 800 may be stiffer nearer the corner 802 because it may be constructed from one or more different, stiffer materials nearer the corner 802 than the distal ends of the main body portion 816 and/or anchor portion 818. For example, the main body portion 816 may comprise a harder and/or stiffer rubber nearer the corner 802 and a softer and/or more flexible rubber nearer the distal end 834. In this way, the lace-receiving structure 800 may be configured to be more rigid nearer the corner 802 and may be configured to bend and/or deform more easily nearer the distal end 834 of the main body portion 816 and/or the distal ends of the anchor portion 818 than the corner 802.
In some embodiments, the width of the main body portion 816 and/or the anchor portion 818 also or alternatively tapers towards the distal ends of the main body portion 816 and/or the anchor portion 818. In one such embodiment, the width of the main body portion 816 of the exemplary lace-receiving structure 800 tapers towards the distal end 834 of the main body portion 816 (i.e., the width of the main body portion 816 decreases when progressing away from the proximal end 832 towards the distal end 834). In another such embodiment, the width of the anchor portion 818 tapers towards the second end 848 in examples where the main body portion 816 is coupled to the first end 846 of the anchor portion 818 (i.e., the width of the anchor portion 818 decreases when progressing away from the first end 846 towards the second end 848).
The article of footwear 900 comprises a sole structure 902 and an upper 904. The upper 904 is coupled to and extends from the sole structure 902 so as to form a foot-receiving cavity 906 between the sole structure 902 and the upper 904. The foot-receiving cavity 906 is configured to receive a wearer's foot. In some embodiments, the foot-receiving cavity 906 is further configured to expand to initially receive the wearer's foot and thereafter contract to retain the wearer's foot. For example, the article of footwear 900 may include a closure system 907 that is configured to tighten, constrict, and/or otherwise reduce the volume of the foot-receiving cavity 906. As discussed in greater detail below, in some embodiments, the closure system 907 may comprise one or more eyelets 926, an adjustment member 928, and one or more lace receiving members 800.
The footwear 900 may be divided into one or more portions (which may also be referred to as “zones” or “regions”). For example, the portions may include a forefoot portion 908, a midfoot portion 910, and a heel portion 912. The forefoot portion 908 of the footwear 900 may correspond to anterior portions of a foot, including toes and joints connecting metatarsal bones with phalanx bones of the foot. The midfoot portion 910 of the footwear 900 may correspond with an arch area of the foot. The heel portion 912 of the footwear 900 may correspond with posterior portions of the foot, including a calcaneus bone.
The footwear 900 may also be divided into a lateral side 914 and a medial side 916, both of which extend through the forefoot portion 908, the midfoot portion 910, and the heel portion 912. For example,
Sole structure 902 comprises a midsole 918 and an outsole 920. In the illustrated embodiment, the midsole 918 and the outsole 920 are formed as separate components that are fixedly coupled together. This can be accomplished in various ways, including with adhesive, fasteners, stitching, and/or other means for fastening. In other embodiments, the midsole 918 and the outsole 920 may be integrally formed as a unitary component.
The midsole 918 of the sole structure 902 is configured to be positioned under the wearer's foot. As such, the midsole 918 may, for example, be configured to provide cushioning and support. The midsole 118 may be configured to flex and/or elastically deform as the wearer's foot applies pressure upon the midsole 918 and/or as the footwear 900 impacts a ground surface. In some embodiments, the midsole 918 may comprise a relatively flexible foam material.
The outsole 920 of the sole structure 902 is configured to be positioned between the midsole 918 and the ground surface. Accordingly, the outsole 920 may, for example, be configured to provide increased traction and/or to protect the midsole 918. In some embodiments, the outsole 120 may comprise various traction elements (e.g., nubs, ribs, cleats, lugs, patterns, etc.) configured for engaging one or more types of ground surfaces. In some embodiments, the outsole 920 may comprise a flexible polymeric material (e.g., rubber).
In some embodiments, the sole structure 902 may also comprise one or more additional components. For example, the sole structure 902 may include one or more cushioning elements (e.g., a fluid-filled capsule such as an airbag) and/or foam member (e.g., a foam pad).
The upper 904 comprises a throat portion 922 separating the lateral side of the upper 904 and the medial side of the upper 904. The upper 904 also comprises a tongue 924 disposed at least partially within the throat portion 922. In other embodiments, the upper 904 may be formed without a throat portion and/or a tongue.
The upper 904 of the footwear 900 may be formed of various materials. For example, the upper 904 may be formed of one or more of the following materials: textiles, foam, leather, polymers, and/or synthetic leather. In some embodiments, the upper 904 may be formed as a single, unitary component (e.g., by knitting or molding). In other embodiments, the upper 904 may comprise a plurality of components that are coupled together (e.g., by stitching, adhesive, fasteners, etc.).
The upper 904 may be fixedly coupled to the sole structure 902 in various ways. For example, the upper 904 may be attached (e.g., stitched) to a strobel, and the strobel may be attached to the midsole 918 (e.g., with an adhesive). In other embodiments, the strobel may be omitted, and the upper 904 may be attached to a component of the sole structure 902. In some such embodiments, the upper 904 may be attached to the midsole 918 and/or a cushioning element (e.g., an airbag) of the sole structure 902 via adhesive, stitching, and/or other means for coupling.
The closure system 907 may include the lace-receiving structures 800, the eyelets 926 in the tongue 924 and/or upper 904, and the adjustment member 928. The adjustment member 928 may comprise a lace, wire, cable, strap, and/or other tightening element that is configured to be adjusted (e.g., pulled) by a user to tighten the upper 904 (and thereby reduce the volume of the foot-receiving cavity 906). As described above, the lace-receiving structures 800 may be configured to receive the adjustment member 928. Thus, the adjustment member 928 may be configured to extend through the lace-receiving structures 800 (e.g., through the eyelets 812 of the lace-receiving structures 800), and/or the one or more of the eyelets 926 of the upper 904 and/or tongue 924. To fasten and/or secure the footwear 900 to their foot, a user may pull on the adjustment member 928 to tighten the upper 904 around their foot. Specifically, pulling on the adjustment member 928 may force the eyelets 926 and/or eyelets 12 towards one another, thereby constricting the foot-receiving cavity 906. After tightening the footwear 900 to a desired level via the adjustment member 928, a user may secure the adjustment member 928 in a tightened position by, for example, tying the adjustment member 928 in a knot. Alternatively, the closure system 907 may include a locking mechanism that secures the adjustment member 928 in a particular position and does not require a user to tie a knot.
The lace-receiving structure 800 may be included in the forefoot portion 908 of the footwear 900. However, in other embodiments the lace-receiving structure 800 may additionally or alternatively be included in the midfoot portion 910 of the footwear 900. Further, although the footwear 900 is depicted as including four of the lace-receiving structures 800 in
In some embodiments, not all the lace-receiving structures 800 may be the same size and/or shape. For example, as depicted in
As discussed above, lace-receiving structures 800 may be coupled to upper 904. In some embodiments, lace-receiving structures 800 may be fixedly (e.g., permanently) coupled to upper 904 via stitching, adhesive, thermal bonding, and/or other means for fixedly coupling. Specifically, the anchor portion 818 may be directly fixedly coupled to upper 904. However, in other embodiments, lace-receiving structures 800 may be removably coupled to upper 904. When the lace-receiving structures 800 is removably coupled to the upper 904, a user may interchange the lace-receiving structures 800 as desired, such as for lace-receiving structures 800 having different sizes, shapes, designs, surface features, and/or colors. In some such embodiments where the lace-receiving structures 800 are removably coupled to the upper 904, the lace-receiving structures 800 may not be stitched and/or adhered to the upper 904. Instead, the anchor portion 818 may hold the lace-receiving structure 800 in place by virtue of it extending laterally, medially, and/or longitudinally underneath the upper 904.
Specifically, each lace-receiving structure 800 may extend through an aperture 938 (best seen in
In some embodiments, such as is depicted in
By extending under the upper 904, the anchor portion 818 may hold the lace-receiving structure 800 in the footwear 900. Specifically, because the anchor portion 818 may extend underneath the upper 904 when included in the footwear 900, the anchor portion 818 may help prevent and/or restrict the lace-receiving structure 800 from pulling back out of the upper 904 through the aperture 938.
As illustrated in
Main body portion 816 may be configured to extend outside of the foot-receiving cavity 906, through the aperture 938, to an exterior of the footwear 900, and may be configured to further extend above and/or over the upper 904. In particular, the main body portion 816 may be configured to extend above and/or on top of the exterior surface 940 of the upper 904. Specifically, an inner side 828 of the main body portion 816 may be configured to face and/or directly contact the exterior surface 940 of the upper 904. In some examples, the distal end 834 of the main body portion 816 may be configured to extend to the throat portion 922 of the footwear 900. As one example, the main body portion 816 may be configured to extend over one or more of the throat portion 922, the tongue 924, and/or the adjustment member 928.
In some embodiments, the footwear 900 may include a reinforcing element 944 in and/or on the upper 904 that is configured to provide additional structural support for the upper 904 in the region of the upper 904 where the lace-receiving structures 800 attach to the upper 904 (e.g., where the anchor portion 818 of lace-receiving structures 800 extends underneath the exterior surface 940 of the upper). By providing this additional structural support to the upper 904, the reinforcing element 944 may help prevent the lace-receiving structures 800 from pulling through, stretching, tearing, and/or other damaging or deforming the upper 904.
In some embodiments, the reinforcing element 944 may be constructed from and/or may comprise a stiffer and/or harder material than the rest of the upper 904. For example, the upper 904 may be constructed primarily from a knit and/or woven fabric, and the reinforcing element 944 may be constructed from a plastic, rubber, and/or other suitable material for reinforcing the upper 904.
The reinforcing element 944 may be coupled to the exterior surface 940 of the upper 904 in some embodiments. In some such embodiments, the reinforcing element 944 may only cover the exterior surface 940 of the upper 904 and may not extend into the upper 904 below the exterior surface 940 of the upper. However, in other embodiments, the reinforcing element 944 may extend into and/or through the upper 904. For example, the reinforcing element 944 may be at least partially embedded in the fabric of the upper 904. Reinforcing element 944 may additionally or alternatively be coupled to and/or cover the interior surface 942 of the upper 904. In some such embodiments, the first side 842 of the anchor portion 818 may directly physically contact the reinforcing element 944. The reinforcing element 944 may be coupled to the upper 904 via adhesive, stitching, and/or thermal treatment.
In some embodiments, anchor portion 818 of the lace-receiving structure 800 may be directly coupled (e.g., via stitching and/or adhesive) to the reinforcing element 944. However, in other examples, anchor portion 818 may be directly coupled to the fabric of the upper 904 and may only be indirectly coupled to the reinforcing element 944 via the common coupling to the upper 904.
In some embodiments, the reinforcing element 944 may extend up to and/or beyond the distal end of the anchor portion 818 (e.g., the first end 846 of the anchor portion 818 when the main body portion 816 is coupled to the second end 848 of the anchor portion 818). In other embodiments, the reinforcing element 944 may only partially cover the anchor portion 818 and the anchor portion 818 may extend and/or project past the reinforcing element 944. In some embodiments, the reinforcing element 944 may at least partially surround, abut, and/or be adjacent to the aperture 938 through which the lace-receiving structure 800 is configured to extend. For example, as illustrated in
Referring to
Thus, the main body portion 816 may be configured to pivot relative to the upper 904. In some such embodiments, the main body portion 816 may be configured to pivot away from the upper 904 as the adjustment member 928 is loosened and/or pivot towards the upper 904 as the adjustment member is tightened.
The footwear 900 can be configured in one or more sizes (e.g., U.S. women's size 4-12) and/or widths (e.g., A, B, C, D, E, EE, and/or EEE). The footwear 900 can also be also be configured in other sizing conventions (e.g., UK, EUR, cm, etc.) and/or sizes (e.g., U.S. men's size 1-18).
