In addition, the disclosed systems, methods, and components thereof are not limited to any specific aspect or feature or combinations thereof, nor do the disclosed things and methods require that any one or more specific advantages be present or problems be solved.
As used in this application the singular forms “a,” “an,” and “the” include the plural forms unless the context clearly dictates otherwise. Additionally, the term “includes” means “comprises.” Further, the term “coupled” or “secured” encompasses mechanical and chemical couplings, as well as other practical ways of coupling or linking items together, and does not exclude the presence of intermediate elements between the coupled items unless otherwise indicated, such as by referring to elements, or surfaces thereof, being “directly” coupled or secured. Furthermore, as used herein, the term “and/or” means any one item or combination of items in the phrase.
As used herein, the term “exemplary” means serving as a non-limiting example, instance, or illustration. As used herein, the terms “e.g.,” and “for example,” introduce a list of one or more non-limiting embodiments, examples, instances, and/or illustrations.
Although the operations of some of the disclosed methods are described in a particular, sequential order for convenient presentation, it should be understood that this manner of description encompasses rearrangement, unless a particular ordering is required by specific language set forth below. For example, operations described sequentially may in some cases be rearranged or performed concurrently. Moreover, for the sake of simplicity, the attached figures may not show the various ways in which the disclosed things and methods can be used in conjunction with other things and methods. Additionally, the description sometimes uses terms like “provide” and “produce” to describe the disclosed methods. These terms are high-level descriptions of the actual operations that are performed. The actual operations that correspond to these terms will vary depending on the particular implementation and are readily discernible by one of ordinary skill in the art having the benefit of this disclosure.
As used herein, the directional terms (e.g., “upper” and “lower”) generally correspond to the orientation of an article of footwear or sole assembly as it is configured to be worn by a wearer. For example, an “upwardly-facing surface” and/or an “upper surface” of a sole assembly refers to the surface oriented in the “superior” anatomical direction (i.e., toward the head of a wearer) when the article of footwear is being worn by the wearer. Similarly, the directional terms “downwardly” and/or “lower” refer to the anatomical direction “inferior” (i.e., toward the ground and away from the head of the wearer). “Front” means “anterior” (e.g., towards the toes), and “rear” means “posterior” (e.g., towards the heel). “Medial” means “toward the midline of the body,” and “lateral” means “away from the midline of the body.” “Longitudinal axis” refers to a centerline of the article from the heel to toe Similarly, a “longitudinal length” refers to a length of the article along the longitudinal axis and a “longitudinal direction” refers to a direction along the longitudinal axis.
As used herein, the term “sole structure” refers to any combination of materials that provides support for a wearer's foot and bears the surface that is in direct contact with the ground or playing surface, such as, for example, a single sole; a combination of an outsole and an inner sole; a combination of an outsole, a midsole, and an inner sole; and a combination of an outer covering, an outsole, a midsole and an inner sole.

Exemplary modalities of fixed attachment may include joining with permanent adhesive, stitches, welding or other thermal bonding, and/or other joining techniques. In addition, two components may be “fixedly attached” or “fixedly coupled” by virtue of being integrally formed, for example, in a molding process. In contrast, the terms “temporarily attached,” “temporarily coupled,” or “temporarily fixed,” refer to two components joined in a manner such that the components can be readily separated from one another to return to their separate, discrete forms without destroying and/or damaging either component. Exemplary modalities of temporary attachment may include removable stitches or other temporary joining techniques.
As used herein, the terms “articles of footwear” or “articles” mean any type of footwear, including, for example, running shoes, soccer shoes, football shoes, rugby shoes, basketball shoes, baseball shoes, sneakers, hiking boots, sandals, socks, 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.

The Disclosed Technology
An article of 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 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.
In use, a wearer's foot applies various forces to the sole structure and/or the upper. These forces can vary depending on the type of use and/or the physical characteristics (e.g., size, strength) of the wearer.
Typically, an upper of an article of footwear is made of one or more relatively thin, flexible materials. These materials allow the upper to bend and flex as the wearer moves and applies forces to the upper.
In some instances, it is desirable to allow one or more portions of the upper of an article to elastically deform (e.g., stretch) at least to some extent when forces are applied thereto. This can, for example, improve comfort. In other instances, it is desirable to limit or prevent one or more portions of the upper of the article from elastically deforming when forces are applied thereto. This can, for example, improve support and/or prevent the wearer's foot from slipping relative to the upper, the sole structure, and/or some other component of the article.
Due to the complex movements of a wearer's foot, it can be difficult to find the right balance of rigidity and stretchability. This difficulty is compounded in activities in which the wearer performs multiple types of movement. For example, when playing basketball, a wearer performs a number of complex movements, including running forward and backward, cutting side-to-side, jumping, pivoting, and stopping. Each of these movement exerts different types and magnitudes of forces on the article. Participants in other sports, such as tennis, soccer, football, baseball, volleyball, etc., move in similar but unique ways.
Thus, some shoes have an upper with rigidity/stretchability configured for one type of movement (e.g., running forward), but it may leave the upper too rigid for other types of movement (e.g., cutting side-to-side) and/or too stretchable for yet other types of movement (e.g., jumping). Some other shoes may have an overall rigidity/stretchability that is suitable for multiple movements, but they do allow for fully customized tuning in multiple directions.
Disclosed herein are articles of footwear that have an upper that can be fully customized in multiple directions and/or for multiple types of movement. As a result, the disclosed articles of footwear provide improved comfort, performance, and durability compared to typical shoes.
In one representative embodiment, an article of footwear includes a sole structure and an upper coupled to the sole structure. The upper includes a base layer and a plurality of support members. The base layer has a peripheral portion. The support members have end portions and an intermediate portion extending between the end portions. The end portions of the support members are coupled to the peripheral portion of the base layer. Each of the intermediate portions of the support members intersect with one or more other ones of the support members and is independently movable between a relaxed state and an engaged state relative to the one or more other ones of the support members.
In some embodiments, the plurality of support members includes a first plurality of support members oriented in a first axial direction, a second plurality of support members oriented in a second axial direction, a third plurality of support members oriented in a third axial direction, and a fourth plurality of support members oriented in a fourth axial direction, and the first axial direction, the second axial direction, the third axial direction, and the fourth axial direction intersect with each other.

Additional examples of the disclosed technology are described below with reference to the accompanying drawings.
Exemplary Embodiments of the Disclosed Technology
Referring now to
In some embodiments, the sole structure can also comprise one or more additional components. For example, in the illustrated embodiment, the sole structure 102 comprises a first cushioning element 112 (e.g., an fluid-filled capsule (e.g., an airbag) or foam member), a second cushioning element 114 (e.g., an fluid-filled capsule (e.g., an airbag) or foam member), and a stability member 116. In other embodiments, the sole structure can additional components (e.g., additional cushioning elements) and/or omit one or more of the components of the sole structure 102 (e.g., the first cushioning element 112 and/or the second cushioning element 114).
In the illustrated embodiment, the midsole 110 comprises perforations 118 and an opening 120 in the heel portion. The perforations 118 can, for example, reduce weight of the midsole 110. The perforations 118 can also allow the first cushioning element 112 to be visible from the bottom of the shoe in embodiments with an opaque or translucent outsole 108. The opening 120 can, for example, reduce the amount of material between the second cushioning element 114 and the wearer's foot, thereby improving the feel and/or responsiveness of the article of footwear 100.
The upper can be fixedly coupled to the sole structure in various ways. For example, in some embodiments, the upper can be attached (e.g., stitched) to a strobel, and the strobel can be attached to the midsole (e.g., with an adhesive). In other embodiments, the upper can be attached to a component of the sole structure. For example, as shown in
One or more portions of the support members 106 can be coupled to base layer 126 (e.g., stitched, adhered, etc.), as further explained below. The support members 106 can be used to customize the stretchability (e.g., elastic deformation) of the base layer 126 in one or more directions. This due to the fact the support members are relatively less stretchable (e.g., elastic) than the base layer 126.
The base layer 126 of the upper 104 can be relatively thin, stretchable material. In some embodiments, the base layer 126 can be configured to elongate to the same extent in a plurality of directions. In other words, when a force is applied to the base layer in a first direction (e.g., tension in the anterior/posterior direction) the base layer elongates in the first direction to the same extent as when the force is applied to the base layer in a second direction (e.g., tension in the medial/lateral direction). In other embodiments, the base layer 126 can be configured to elongate to a different extent in one direction than one or more other directions when the same force is applied the respective directions.
As shown in
In some instances, the intermediate portions 134 of the support members 106 can be completely uncoupled to the base layer 126. In other embodiments, the intermediate portions 134 of the support members 106 can comprise one or more tack stitches 142 (
Referring to
The strands 106a-106d intersect, but the strands can all move independently relative to each other. As one example, the first strands 106a can move independently relative to the second strands 106b, the third strands 106c, and the fourth strands 106d, and likewise for the other strands.
In some embodiments, when the upper 104 of the article of footwear 100 is not under any load or movement, one or more of the support members 106 can be in a relaxed state. In the relaxed state, the support members 106 are slackened, as shown in
The tension of each strand of the support members 106 or each group of strands can be individually selected to customize the fit and performance of the upper 104. Also, the various properties (e.g., thickness, material, cross-sectional profile) of the support members can be individually selected to customize the fit and performance of the upper 104.
In some embodiments, the tension of one group of strands can be the same as one or more of the other groups of strands when the groups of strands are in the relaxed state. In this manner, the base layer 126 tends to elongate evenly in a plurality of directions (assuming the base layer 126 uniformly elongates without the support members 106 coupled thereto and that the strands have uniform properties). In other embodiments, the tension of one group of strands can be different than one or more other groups of strands. In this manner, the base layer 126 tends to elongate more in the direction where the strands have less tension in the relaxed state than in the direction in which the strands have more tension in the relaxed state (assuming the base layer 126 uniformly elongates without the support members 106 coupled thereto and that the strands have uniform properties).
If stretch is not desired in a particular direction, the support members 106 oriented in that direction can be in the engaged state when the article of footwear has no external forces applied thereto.
The support members 106 can be oriented at various angles relative to each other. For example, in some embodiments, the first strands 106a and the second strands 106b can intersect at an angle between 70-110 degrees or more particularly at an angle between 80-100 degrees. In particular embodiments, the first strands 106a and the second strands 106b intersect at an angle of 90 degrees. In some embodiments, the first strands 106a and the third strands 106c intersect at an angle between 25-65 degrees or more particularly at an angle between 25-55 degrees. In some embodiments, the first strands 106a and the third strands intersect at an angle of 45 degrees. In some embodiments, the first strands 106a and the fourth strands 106d intersect at an angle between 25-65 degrees or more particularly at an angle between 25-55 degrees. In some embodiments, the first strands 106a and the fourth strands 106d intersect at an angle of 45 degrees.
As shown in
Although the illustrated embodiments show strands oriented in four directions, other embodiments may have strands oriented in more or less than four directions. Also, in some embodiments, an article of footwear can have support members disposed on only one portion of the upper (e.g., a toe portion) and have one or more other portions without support members (e.g., a heel portion).
In view of the many possible embodiments to which the principles of the disclosure may be applied, it should be recognized that the illustrated embodiments are only examples and should not be taken as limiting the scope of the claims. Rather, the scope of the claimed subject matter is defined by the following claims and their equivalents.
