Zusammenfassung: | A shoe has an insole having a heel in a customary supportive hard rubber-like material about 3 inches thick. The same rubber-like material surrounds the entire sole with a change in thickness beginning at the arch, where it slopes down, leveling out at a thickness of about 1¼ inches. This change in thickness creates a frontal recess, leaving a bead of rubber at the outer edge. This cavity holds a thick cushion of about 1¾ inches of highly viscous gel material held in place by the rubber lip and adhered to the elastic material. This creates a cushion when the foot applies weight. The front of the sole and the back of the heel are equal in height, giving the entire surface equal height planes for balance. The two materials are one rubber like, one gel like and slope toward each other at the arch in identical angles. |
