ABSTRACT:
A sole for a shoe is discosed which is constructed with a relatively rigid top layer or insole and a relatively rigid bottom layer or outsole which are mounted for relative rotation about an axis perpendicular to and extending through the center of the sole. Between the insole and outsole, there is provided a relatively yieldable elastomer layer, which permits relative rotation between the insole and the outsole upon rotation of the foot during walking, but will resiliently restore the insole and outsole to an aligned position when the torsional force of the foot is removed.
