An article of footwear includes a navicular support structure on a medial side. The navicular support structure includes a non-stretch, tensioned material that reduces an interior volume of the upper of the article of footwear and redirects applied forces from the midfoot region of the article of footwear to other regions, such as the forefoot region.

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.

An article of footwear comprises a sole structure and an upper. The upper is connected to the sole structure to form an enclosure to at least partially receive a foot. The upper comprises a first panel, a second panel, a backing panel and fibers. The first panel and the second panel at least partially form the enclosure. The backing panel is located within the enclosure along surfaces of the first and second panels. The fibers extend from the backing panel and are mechanically embedded in the first and second panels so that at least some of the fibers are partially disposed outside the enclosure.

An article of footwear including a tensioning system is disclosed. The tensioning system is adjustable and includes a first layer and a second layer that is moveable and extends over the first layer. The article can include elements that are capable of distributing tension over the article. The article may include a tensile element, guide elements, and one or more strap guides attached to an underside of the second layer.

An article of footwear comprises a sole structure and an upper. The upper is connected to the sole structure to form an enclosure to at least partially receive a foot. The upper comprises a first panel forming a first portion of the upper and having a first texture, a second panel forming a second portion of the upper and having a second texture, and an embroidery area extending across portions of the first panel and the second panel and having an appearance that replicates the first texture extending into the second texture.

Described are shoes for ball sports including an upper having an outer surface. An actuator is configured to change at least one surface property of a portion of the outer surface of the upper, and a sensor is configured to be sensitive to movements of the shoe. A processing unit is connected to the actuator and the sensor and configured to process sensor data retrieved from the sensor and to cause the actuator to change the at least one surface property of the portion of the outer surface of the upper if a predetermined event is detected in the sensor data.

An upper structure for a shoe that improves foot fit and hold of an upper at the time of turn motion. In an upper 2 that covers a foot of a shoe wearer, an expandable part 20 is provided at a midfoot region M that corresponds to a midfoot portion of the foot, and a non-expandable part 21 is provided at a lateral side region and a medial side region except for the midfoot region M. A boundary surface between the expandable part 20 and the non-expandable part 21 is formed by a substantially flat surface. At the boundary surface, respective end portions 20E, 21E of the expandable part 20 and the non-expandable part 21 are sewn together such that a seam does not appear on the boundary surface.
