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.

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.

A strobel for an article of footwear includes a base layer and an upper layer formed of a polymer material covering a portion of the top surface of the base layer, leaving a portion of the top surface of the base layer exposed about an entire periphery of the base layer. The upper layer is directly bonded to the base layer without any fastening members. A method of forming the strobel is also disclosed.

An article of footwear may include a sole assembly and an upper, positioned above the sole assembly, formed from a stretchable material such as a stretchable canvas. The upper may include stitching, with a stretchability of the stretchable canvas being maintained in an area of the upper where the stitching extends. The stitching may include, for example, double needle cover stitching.

Embodiments of the present invention relate to a thermoplastic polyurethane (“TPU”) infused mesh material that is molded to form at least a portion of a shoe. The TPU infused mesh may be formed as an upper, a portion of sole or other components of a shoe. The TPU infused mesh is formed, in an exemplary embodiment, through the application of liquid TPU to a surface of a spacer mesh. The liquid TPU infused spacer mesh is then cured, cut to a pattern, and heat molded to form a desired portion of the shoe. The heat molded TPU mesh is coupled to other portions of the shoe (e.g., sole) to form an article footwear in an exemplary embodiment.
