DETAILED DESCRIPTION
[00015] The present detailed description generally describes embodiments of methods of making an article of footwear and articles of footwear made by such methods. For simplicity purposes, "article of footwear" and "footwear" may be used interchangeably. Additionally, references to a singular item or characteristic is not limited to a singular term. Singular reference to an item or characteristic may include the plurality of such item or characteristic. Similarly, plural references to items or characteristics may include the singular of such items or characteristics. Singular and plural forms may be used interchangeably without changing the meaning or scope of the invention.
[00016] As shown in FIGS. 1 and 2, in some embodiments articles 100 may include an upper 102 and a sole structure 104. For purpose of reference, upper 102 and/or article of footwear 100 generally may be divided into a forefoot portion 160, a midfoot portion 162, and a heel portion 164. Forefoot portion 160 generally may be associated with a toe box for the toes and joints connecting the metatarsals with the phalanges. Midfoot portion 162 generally may be associated with the instep and/or arch of a foot. Heel portion 164 generally may be associated with the heel of a foot, including the calcaneus bone. Upper 102 also generally may include a lateral side portion 166 and a medial side portion 168. Lateral side portion 166 and medial side portion 168 may be opposing side of upper 102. One or both lateral side 166 and medial side 168 may extend through forefoot portion 160, midfoot portion 162, and heel portion 164. Some embodiments further may include a front toe portion 154 as well as a vamp or instep portion 156
[00017] Sole structure 104 may be secured to upper 102 and extend between the foot and the ground surface when article 100 is worn. In some embodiments, sole structure 104 may be configured to provide traction for article 100. In some embodiments, sole structure 104 may be configured to absorb or attenuate impact or other ground reaction forces when compressed between the foot and the ground surfaces during walking, running, or other ambulatory activities. [00018] The configuration of sole structure 104 may vary significantly in different embodiments to include a variety of known or newly developed sole structures and/or components. For example, as shown in FIG. 2, sole structure 104 variously may include an outsole 22, a midsole 21, and/or an insole 23. Midsole 21 is secured to a lower surface of upper 102 and may be formed from a compressible polymer foam element (e.g. a polyurethane or ethyl vinylacetate 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 other configurations, midsole 21 may incorporate fluid-filled chambers, plates, moderators, or other elements that further attenuate forces, enhance stability, or influence the motions of the foot, or midsole 21 may be primarily formed from a fluid-filled chamber. Outsole 22 is secured to a lower surface of midsole 21 and may be formed from a wear-resistant rubber material that is textured to impart traction. Insole 23 is located within upper 102 and is positioned to extend under a lower surface of the foot. The structure and features of sole structure 104 or any sole structure utilized with upper 102 may vary considerably.
[00019] In some cases, the configuration of sole structure 104 may be selected to be suitable for one or more types of ground surfaces on which sole structure 104 may be used. Example ground surfaces may include, but are not limited to, natural turf, synthetic turf, dirt, sand, gravel, snow, ice, as well as other surfaces. The sole may be made from a combination of natural rubber, polyurethane, or polyvinyl chloride (PVC) compounds.
[00020] Upper 102 may be configured to receive and cover a foot. In some embodiments, upper 102 may include an opening 106 that provides entry to an interior of upper 102. For example, as shown in FIG. 1, in some embodiments opening 106 may be an ankle opening. Upper may be made from one or more of a textile, polymer foam, polymer sheet, leather, synthetic leather, elastic leather.
[00021] In some embodiments, upper 102 may include a fastening or closure or other provisions for tightening or otherwise adjusting fit characteristics (e.g. girth) of upper 102. For example, in some embodiments upper 102 may include tensioning members, such as lacing members 122 and eyelets 124 for receiving one or more lace or other tensioning member (such as a cable) 126. In this manner, a size of opening 106, and corresponding girth of upper 102 may be adjusted to customize a fit of upper 102 and article of footwear 100. In some embodiments, lacing members 122 of the closure structure may provide reinforcing edge structure and form an opening having a V-shaped configuration, a U-shaped configuration, or another configuration. [00022] In some embodiments, upper 102 may include a tongue 130 (illustrated in phantom in FIG. 1). Tongue 130 may be disposed between a fastening or closure structure and a foot to facilitate comfort and fit. For example, tongue 130 may be disposed between lacing members 122 and a foot - between eyelets 124 and a foot - or between lacing 126 and a foot received in the interior of upper 102. It will be appreciated that a tongue may be optional in some embodiments.
[00023] Bootie 140 may extend through each of a bootie forefoot region (or forefoot portion) 142, a bootie midfoot region (or midfoot portion) 144, and a bootie heel region (or heel portion) 146, and along with both a bootie lateral side (or lateral portion) 148 and a bootie medial side (or medial portion) 150. In some embodiments, bootie 140 may also include tongue 130. In some embodiments, bootie 140 may be substantially formed by one material textile, polymer foam, polymer sheet, leather, synthetic leather) into a seamless bootie 140, or from multiple material elements (e.g., textiles, polymer foam, polymer sheets, leather, synthetic leather) that are joined through stitching or bonding as bootie 140, for example.
[00024] As used in this description, the terms forefoot portion or region, midfoot portion or region, heel portion or region, toe portion or region, and instep portion or region are only intended for purposes of description and are not intended to demarcate precise portions or boundaries of upper 102. Likewise, the terms lateral side (or lateral portion) and medial side (or medial portion) are intended to represent generally two sides of an article, rather than precisely demarcating upper 102 into two halves.
[00025] The article of footwear of the present invention has a flap portion that extends from the medial midfoot region around the forefoot region to and including the lateral midfoot region. The flap portion may be attached and detached from a lip portion that extends from the sole of the footwear. In some embodiments herein, an article of footwear may be a medical footwear. In another embodiments, the article of footwear may be athletic footwear.
