An article of footwear and a method of manufacturing the article of footwear are disclosed. The footwear may include an upper and a sole structure. The upper incorporates a textile element with edges that are joined together to define at least a portion of a void for receiving a foot. The textile element may also have a first area and a second area with a unitary construction with varying stitch configurations. The upper may also incorporate longitudinal ribs extending along the lateral and/or medial sides of the upper. Various warp knitting or weft knitting processes may be utilized to form the textile element.

An article of footwear having an upper comprising leno woven fabric. The leno woven fabric may be a single layer leno woven fabric. The leno woven fabric may have a pattern to provide desired characteristics, such as but not limited to, ventilation, thermal conductivity, stretchability, strength, moisture wicking, and/or antimicrobial protection. The pattern may be non-uniform to provide varying degrees of one or more of these characteristics. Methods for manufacturing an article of footwear including an upper comprising leno woven fabric are also provided.

Articles of footwear, including athletic footwear, include one or more of: (a) a sole structure; (b) an upper having lateral and medial side elements engaged with the sole structure, the upper made from a polymer matrix structure that extends through at least a heel region; (c) a size adjustment mechanism located at the heel region; (d) a heel tongue element located adjacent the size adjustment mechanism; (e) a shoe securing mechanism; (f) an instep tongue member; and/or (g) a bootie member located at least partially within the foot-receiving chamber. Methods of manufacturing such articles of footwear also are disclosed.

A method of manufacturing an article of footwear is disclosed. The footwear may include an upper and a sole structure. The upper incorporates a textile element with flat-knit edges that are joined together to define at least a portion of a void for receiving a foot. The textile element may also have a first area and a second area with a unitary construction. The first area is formed of a first stitch configuration, and the second area is formed of a second stitch configuration that is different from the first stitch configuration to impart varying textures to a surface of the textile element. Various warp knitting or weft knitting processes may be utilized to form the textile element.

A shoe includes a sole, an upper, and a welt. The sole and upper define a seam. The welt overlies the seam. The sole includes flex grooves. The upper includes perforations. The welt includes flex slits.

A forced-air footwear is presented and comprises a foot supporting portion including a sole with cavities therein covered with a foot-contacting layer, and a channel communicating between the cavities and the interior of the footwear to allow air flow between the cavities and the interior of the footwear; a foot covering portion, the foot covering portion including a valve allowing air passage therethrough in a single direction, the cavities including a compressed configuration, when supporting a weight of a wearer, and an expanded configuration when not supporting the weight of a wearer, the passage between the compressed configuration and the expanded configuration forcing an air movement of the air contained in the cavities, the valve blocking the air movement in one direction, wherein the compression of the cavities and the blocking action of the air by the valve is forcing air through the footwear.

A method of forming a traced element is disclosed. The method may include printing layers of a traced element and incorporating a textile strand in overlapping polymer layers of the traced element. In some embodiments, the traced element may be formed on a base layer. The traced element may be incorporated into an upper for an article of footwear.

A footwear (10) comprises an upper arrangement (20) and a sole (30), in which the upper arrangement (20) comprises an upper material (12) comprising in a lower peripheral area at least one air permeable portion (14), an air-permeable layer (16) arranged in a lower area of the upper arrangement (20) on the sole side above the sole (30), wherein the air-permeable layer (16) is water vapor permeable and has a three-dimensional structure that permits passage of air at least in the horizontal direction; and at least one water vapor permeable functional layer (18) arranged on an inner side of the upper material (12) and above the air-permeable layer (16). The at least one air permeable portion (14) enables the air permeable layer (16) to communicate with the outer surroundings such that air is exchanged between the outer surroundings and the air permeable layer (16), said air permeable portion (14) further enables the water vapor permeable functional layer (18) to communicate with the outer surroundings such that water vapor is transported from an inner side of the functional layer (18) to the outer surroundings. A water vapor permeable first protective layer (22) is arranged between the air permeable portion (14) and the functional layer (18) in at least an area of the air permeable portion (14) above the air-permeable layer (16), wherein the first protective layer (22) is adapted for protecting the functional layer (18) against particles penetrating through the air permeable portion (14).
