Abstract: Foot support systems (and articles of footwear including them) include a midfoot flex component, such as a bi-stable spring element, that moves the article of footwear/sole structure/foot support component/midfoot flex component between an open position/foot insertion or removal configuration and a closed position/foot supporting configuration and vice versa.

Abstract: An article of footwear includes a sole structure and an upper. The upper is coupled to the sole structure so as to form a foot-receiving cavity therebetween. The upper comprises a first portion, a second portion, and an expandable panel disposed between the first portion and the second portion. The upper is movable between a compressed configuration and an expanded configuration. In the compressed configuration, the first portion and the second portion are coupled together at a location adjacent to the expandable panel and the expandable panel is collapsed. In the expanded configuration, the first portion and the second portion are spaced apart from each other at the location adjacent to the expandable panel and the expandable panel is exposed. One or more dimensions of the foot-receiving cavity are larger when the upper is in the expanded configuration than when the upper is in the compressed configuration.

Abstract: A component, for example, a shoe foxing, may have one or more regions with embedded particles and one or more regions without embedded particles. The one or more regions without embedded particles may comprise one or more outer surfaces of the component. The component may be formed by heating and pressing material sections in a mold. The component may be formed by extrusion. One or more of the material sections may lack embedded particles.

Abstract: A shoe with a three-dimensional (3-D) surface texture created using rapid manufacturing techniques is provided. A plurality of 3-D surface texture options is presented on a user interface; each of the options is associated with one of a plurality of 3-D surface textures to be applied to a portion of a shoe. A selection of a 3-D surface texture is received and is used in part to generate a design file. The design file is used to instruct a rapid manufacturing device to manufacture the portion of the shoe comprised of the 3-D surface texture using a rapid manufacturing technique.
