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.

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, andthe 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. 2. The footwear assembly as recited in claim 1 wherein the shell and the plurality of particles are collectively structured to define variable configurations of the shell dependent at least in part on foot pressure being applied to the outer sole. 3. The footwear assembly as recited in claim 1 wherein the hollow interior extends in underlying relation to at least the majority of the inner sole. 4. The footwear assembly as recited in claim 2 wherein the inner sole is dimensioned and structured to at least partially conform to a configuration of underlying, correspondingly disposed portions of the plurality of particles at least upon an application of foot pressure to the inner sole. 5. The footwear assembly as recited in claim 2 wherein the inner sole comprises a flexible material having sufficiently reduced thickness to at least partially conform to a configuration of the correspondingly disposed plurality of particles and to a corresponding portion of a wearer's foot upon an application of foot pressure to the inner sole. 6. The footwear assembly as recited in claim 1 wherein the inner sole and the plurality of particles are collectively structured to define a variable configuration of the shell dependent at least in part upon an application of foot pressure to the outer sole. 7. The footwear assembly as recited in claim 6 wherein the shell and the plurality of particles are collectively structured to define variable configurations of the shell dependent at least in part upon a location of an application of foot pressure to the inner sole. 8. The footwear assembly as recited in claim 7 wherein the inner sole comprises a flexible material having a sufficiently reduced thickness to at least partially conform to a configuration of the corresponding plurality of particles and to a corresponding portion of a wearer's foot upon an application of foot pressure to the inner sole. 9. The footwear assembly as recited in claim 1 wherein the plurality of particles are formed of a rigid non-deformable material. 10. The footwear assembly as recited in claim 9 wherein the shell is formed of a flexible material having sufficient resiliency to extend laterally outward towards corresponding sides of the upper upon an application of foot pressure to the outer sole. 11. The footwear assembly as recited in claim 10 wherein the shell is sufficiently resilient to move between the laterally outward extension and a substantially normal, non-compressed orientation upon a reduction of foot pressure to the outer sole. 12. A footwear assembly structured to require stability adjustment by a wearer concurrent to an application of foot pressure thereto, the assembly comprising: an upper, an inner sole, and an outer sole, the upper structured for retention on a foot of a wearer,the outer sole including a hollow interior, the hollow interior substantially filled with a plurality of unconnected free flowing particles,the outer sole including a shell having a base and a side wall formed of a flexible material disposed in retaining, at least partially enclosing relation to the plurality of particles,a tread structure formed on outer exposed portions of the outer sole,the plurality of particles formed of a rigid substantially non-deformable material and disposable into and out of movable engagement with one another and inner surfaces of the shell, andthe inner sole, the shell and the plurality of particles being collectively structured to define variable configurations of the shell dependent at least in part upon an application of foot pressure to different portions of the outer sole,wherein the rigid substantially non-deformable particles and the flexible side wall of the shell cooperate to provide, upon an application of foot pressure to the outer sole, movement of the rigid substantially non-deformable particles within the shell to cause at least a portion of the side wall to extend outwardly into the variable configurations. 13. The footwear assembly as recited in claim 12 wherein the hollow interior extends in underlying relation to at least a majority of the inner sole, the inner sole comprising sufficient flexibility to at least partially conform to correspondingly disposed portions of the plurality of particles upon foot pressure being applied thereto. 14. The footwear assembly as recited in claim 13 wherein the inner sole, the plurality of particles and the shell are cooperatively disposed and dimensioned to facilitate a massaging action being applied to the foot during walking. 15. The footwear assembly as recited in claim 12 wherein the flexible material of the shell is sufficiently resilient to have different portions thereof extend laterally outward and beyond corresponding sides of the upper upon an application of foot pressure to different portions of the outer sole. 16. The footwear assembly as recited in claim 15 wherein the shell is sufficiently resilient to move between said laterally outward extension and a normal, substantially non-compressed orientation. 17. The footwear assembly as recited in claim 12 wherein the flexible material of the shell is sufficiently resilient to move between a compressed orientation and a non-compressed orientation, the compressed orientation comprising at least a portion of the shell and some of said plurality of particles retained therein extending laterally outward and beyond a corresponding side of the upper. 18. The footwear assembly as recited in claim 17 wherein the compressed orientation being at least partially defined by an application of foot pressure to at least the portion of the shell, the non-compressed orientation being at least partially defined by a reduction of foot pressure on the outer sole. 19. The footwear assembly as recited in claim 17 wherein the flexible material of the shell is sufficiently resilient to normally bias the shell into the non-compressed orientation. 20. The footwear assembly as recited in claim 12 wherein the plurality of particles are disposed in an enclosed relation within the hollow interior by the inner sole and the shell. 21. The footwear assembly as recited in claim 12 wherein the plurality of particles are generally spherical.
