Articles of footwear with localized traction regions. An article of footwear includes an upper with a shell and a sole assembly coupled to the upper. The sole assembly includes an outsole with a traction surface and a heel region from which a heel projects. The sole assembly and the upper collectively define a foot compartment. The traction surface includes a plurality of distinct localized traction regions, each of which has a traction coefficient that is different than that of at least one other localized traction region. The traction surface further defines and/or includes a stirrup glide surface. The stirrup glide surface is configured to permit the article of footwear to be selectively inserted into and removed from a stirrup of a saddle by sliding along a tread surface of the stirrup without obstruction by the stirrup.

A first item of footwear is provided including a midsole; an upper, releasably coupled to the midsole; and a sole releasably coupled to the midsole. A second item of footwear is provided including a sole; an upper, releasably coupled to the sole; and a toe support releasably coupled to the sole. A third item of footwear is provided including: a sole; a first upper portion attached to the sole; and a second upper portion releasably coupled to first upper portion, such that the second upper portion can be coupled to the first upper portion while the shoe is being worn.

An article of footwear includes an upper and a sole structure attached to the upper. The article of footwear also includes a cradle having a base extending between the upper and the sole structure, a first sidewall extending from the base and along a first side of the upper, and a second sidewall extending from the base along a second side of the upper, each of the first sidewall and the second sidewall including a plurality of eyelets. The article of footwear further includes a cable operable to move the upper between a relaxed state and a tightened state. The cable including a first strand extending through at least one of the eyelets of the first sidewall and a second strand extending through at least one of the eyelets of the second sidewall.

Footwear includes one or more of: (a) an upper portion at least partially defining a foot-receiving chamber; (b) a track component integrally formed or engaged with the upper portion; (c) a heel engaging component movable with respect to the upper portion via the track component between a closed configuration and an open configuration; (d) a locking system, e.g., holding the heel engaging component in the closed configuration; (e) a biasing system, e.g., applying force to the heel engaging component toward the open configuration; (f) a stop system, e.g., keeping the heel engaging component from completely disengaging from the track component; and/or (g) a sole structure. When the footwear is supported upright on a horizontal surface, the heel engaging component may move rearward (and in some examples upward) via the track component when changing from the closed to the open configuration.

The present invention is directed to an adjustable footwear system to provide varying degrees of tightness in different areas of the footwear before and after the footwear is received on the foot. An extensor system is activated to open or close a cavity of the footwear between the upper and an insole. The extensor system can provide loosen the footwear to the foot.

The present invention is directed to an adjustable footwear system to provide varying degrees of tightness in different areas of the footwear before and after the footwear is received on the foot. The footwear is, in its initial form, tightest on the inner cavity with an upper comprised of one or more elastic materials. An extensor system is activated to create a rigid infra-structure to open a cavity of the footwear between the upper and an insole. A decrease of pressure in the extensor system decreases the cavity volume and allows for the elastic upper to apply pressure to the foot.
