Footwear assembly

摘要

A footwear assembly requires a wearer to adjust in order to maintain stability while standing, walking, etc. The assembly includes an outer sole having a flexible shell surrounding a hollow interior substantially filled by a plurality of unconnected, substantially non-deformable particles. Foot pressure applied to the outer sole results in movement of the plurality of particles, and the resiliency of the shell allows it to assume a variety of different configurations based in part on the portion to which pressure is applied. The resiliency of the shell further facilitates normal biasing thereof and the particles therein into a normal, non-compressed orientation. The tendency of the outer sole to assume a variety of different configurations will, in some circumstances, require a wearer to adjust the corresponding foot and/or leg in order to maintain normal stability, at least when foot pressure is applied to the outer sole.

主权项

1. A footwear assembly structured to require stability adjustments of a wearer while in use, the footwear assembly comprising:
an upper, an outer sole, and an inner sole disposed in segregating relation between the upper and the outer sole, the outer sole including a hollow interior and a particulate filler disposed therein, the particulate filler comprising a plurality of unconnected free flowing particles, the hollow interior of the outer sole is substantially filled with the plurality of particles, the plurality of particles formed of a nondeformable material disposable into and out of movable engagement relative to one another and relative to an inner surface of the outer sole at least upon an application of foot pressure to the outer sole, and the outer sole including a shell having a base and an upwardly extending side wall formed of a flexible material and disposed in retaining relation to the plurality of particles, wherein at least a portion of the side wall is deformed outwardly beyond a periphery of the inner sole as a result of outward movement of at least some of said plurality of particles within the shell upon an application of foot pressure to the outer sole.
