The present application relates generally to footwear having an upper and a support flap configured for securement of the upper around a foot.
This section provides background information related to the present disclosure which is not necessarily prior art.
Footwear may include a sole structure configured to be located under a wearer's foot to space the foot away from the ground. A footwear upper attached to the sole structure receives the foot. The fit of the upper to the foot may be adjusted with a closure system so that the upper is loose enough to receive the foot but can be tightened around the foot to secure the foot relative to the sole structure. A closure system may provide added stability to the footwear to secure the foot.
Sole structures generally include a layered arrangement extending between a ground surface and the upper. One layer of the sole structure includes an outer sole that provides abrasion-resistance and traction with the ground surface. The outsole may be formed from rubber or other materials that impart durability and wear-resistance, as well as enhance traction with the ground surface. Another layer of the sole structure includes a midsole disposed between the outsole and the upper. The midsole provides cushioning for the foot and may be partially formed from a polymer foam material that compresses resiliently under an applied load to cushion the foot by attenuating ground-reaction forces. Sole structures may also include a comfort-enhancing insole or a sockliner located within a void proximate to the bottom portion of the upper and a strobel attached to the upper and disposed between the midsole and the insole or sockliner.
The drawings described herein are for illustrative purposes only of selected configurations and are not intended to limit the scope of the present disclosure.
Corresponding reference numerals indicate corresponding parts throughout the drawings.
Example configurations will now be described more fully with reference to the accompanying drawings. Example configurations are provided so that this disclosure will be thorough, and will fully convey the scope of the disclosure to those of ordinary skill in the art. Specific details are set forth such as examples of specific components, devices, and methods, to provide a thorough understanding of configurations of the present disclosure. It will be apparent to those of ordinary skill in the art that specific details need not be employed, that example configurations may be embodied in many different forms, and that the specific details and the example configurations should not be construed to limit the scope of the disclosure.
The terminology used herein is for the purpose of describing particular exemplary configurations only and is not intended to be limiting. As used herein, the singular articles “a,” “an,” and “the” may be intended to include the plural forms as well, unless the context clearly indicates otherwise. The terms “comprises,” “comprising,” “including,” and “having,” are inclusive and therefore specify the presence of features, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and/or groups thereof. The method steps, processes, and operations described herein are not to be construed as necessarily requiring their performance in the particular order discussed or illustrated, unless specifically identified as an order of performance. Additional or alternative steps may be employed.
When an element or layer is referred to as being “on,” “engaged to,” “connected to,” “attached to,” or “coupled to” another element or layer, it may be directly on, engaged, connected, attached, or coupled to the other element or layer, or intervening elements or layers may be present. In contrast, when an element is referred to as being “directly on,” “directly engaged to,” “directly connected to,” “directly attached to,” or “directly coupled to” another element or layer, there may be no intervening elements or layers present. Other words used to describe the relationship between elements should be interpreted in a like fashion (e.g., “between” versus “directly between,” “adjacent” versus “directly adjacent,” etc.). As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.
The terms first, second, third, etc. may be used herein to describe various elements, components, regions, layers and/or sections. These elements, components, regions, layers and/or sections should not be limited by these terms. These terms may be only used to distinguish one element, component, region, layer or section from another region, layer or section. Terms such as “first,” “second,” and other numerical terms do not imply a sequence or order unless clearly indicated by the context. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the example configurations.
In the discussion that follows, terms “about,” “approximately,” “substantially,” and the like, when used in describing a numerical value, denote a variation of +/−10% of that value, unless specified otherwise.
Referring to the drawings, wherein like reference numbers refer to like components,
In different embodiments, upper 102 may have a variety of different configurations. In particular, upper 102 may have any design, shape, size, and/or color. For example, in the exemplary embodiment, article 100 is a basketball shoe and so, therefore, upper 102 may have a high-top configuration that is shaped to provide high support on an ankle. In other embodiments, however, upper 102 could be configured as a low-top upper for basketball, running, or other activities.
The footwear 10 may be divided into a forefoot region 24, a midfoot region 26, a heel region 28, and an ankle region 32. The forefoot region 24 generally includes portions of the article of footwear 10 corresponding with the toes as well as portions of the article of footwear 10 corresponding with the joints connecting the metatarsals with the phalanges, also known as the ball of the foot. The forefoot region 24 is further divided into toe region 24T and ball region 24B. The midfoot region 26 generally includes portions of the article of footwear 10 corresponding with an arch area 29 and instep 30 of the foot, and the heel region 28 corresponds with rear portions of the foot, including the calcaneus bone. The ankle region 32 corresponds with the ankle. The forefoot region 24, the midfoot region 26, the heel region 28, and the ankle region 32 are not intended to demarcate precise areas of the footwear 10, but are instead intended to represent general areas of the footwear 10 to aid in the following discussion.
The sole structure 100 includes a midsole 34 and an outsole 36. The midsole 34 may be formed from a compressible polymer foam element (e.g., a polyurethane or ethylvinylacetate foam) that attenuates ground reaction forces (i.e., provides cushioning) when compressed between the foot and the ground during walking, running, or other ambulatory activities. In further configurations, the midsole 34 may incorporate fluid-filled chambers, plates, moderators, bladders or other elements that further attenuate forces, enhance stability, or influence the motions of the foot. The midsole 34 may be a single, one-piece midsole, or could be multiple components integrated as a unit. In some embodiments, the midsole 34 may be integrated with the outsole 36 as a unisole. The outsole 36 may be one-piece, or may be several outsole components, and may be formed from a wear-resistant rubber material that may be textured to impart traction and/or may include traction elements such as cleats secured to the midsole 34.
When the foot is positioned within the foot-receiving cavity 104 of the footwear 10, it is supported on a foot-facing surface of the midsole 34. The foot-facing surface of the midsole 34 may be covered by a strobel 114 (shown in
The footwear 10 may further include an anterior end 18 associated with a forward-most point of the forefoot region 24, and a posterior end 20 corresponding to a rearward-most point of the heel region 28. The footwear 10 includes a lateral side 42 (shown in
A throat 120 extends across the top of the upper 102 and defines the instep region 30 extending between the lateral side 42 and the medial side 44 from the foot-receiving cavity 104 to the forefoot region 24. The foot-receiving cavity 104 is formed between a rearmost portion of the upper 102, the lateral side 42, and the medial side 44. Outermost edges of the throat 120 define a collar 124. The collar 124 cooperates with lateral side 42, the medial side 44, and the rearmost portion of the upper 102 to define an interior void 126 (shown in
The upper 102 is tightened and secured around the foot with a closure system 106 that uses at least one flap 108, with flap loops 208 (shown in
Referring to
For example, the tongue 118, first layer 115, and outer layer 116 could be integral portions of a continuous sock upper. Second layer 116 is shown in a cut-away format in
Flap 108 also is shown in greater detail in
Accordingly, the flap 108 may be a transverse flap. The free end 203 of the flap may be a “free” end as it extends away from the outer layer 116 and the upper 102. As used herein, an “end” of a component is not limited to a terminal edge of a component, but instead also includes a portion of the component in the vicinity of the terminal end.
The flap 108 includes one or more cables, e.g., support cables 212. As shown in
It is contemplated that only one finger and lace loop may be present (without a notch), or that more than two fingers and more than one notch are included. For example, flap 108 may include three fingers and two notches, four fingers and three notches, or have another suitable combination of fingers and notches.
The flap 108, particularly each finger 206, is disposed between the first layer 115 and the second layer 116 of the tongue 118, and extends outside of first layer 115 and second layer 116 on both the lateral side 42 and the medial side 44. The tongue 118 extends over the instep region 30, and is disposed between the foot and the flap 108 at the instep region 30. The fingers 208 extend through or over the instep region 30. The flap 108 includes one or more materials that are stiffer than the tongue 118 to enhance a lockdown effect of the flap 108 over the foot, lending stability to the foot within the upper 102. The lockdown effect achieved by the flap 108 provides stability and added support to the article of footwear when lateral forces are applied.
The flap 108 may include a third material with a third elasticity that is less than the first elasticity of the first layer and the second elasticity of the second layer. For example, the flap 108 may be suede, leather, composites, a thermoplastic polyurethane, or the like. The closure system 106 provides an adjustable, secure fit to tighten the upper 102 around the foot, to thereby secure the foot relative to the sole structure 100 underlying the upper 102.
Referring to
Pocket or pockets 502 extend from a medial edge 504 of the tongue 118 to a lateral edge 506 of the tongue 118. It is contemplated that there may be as many pockets 502 as is necessary to receive the fingers 206 of the flap 108, or as set forth above, one large pocket may be configured to receive all of the fingers 206.
The collar 124 includes one or more openings 508 and one or more apertures 510. The openings 508 are disposed on a medial side of the collar 124 and a lateral side of the collar 124. The openings 508 are configured to receive the lace 112 (shown in
