ABSTRACT:
An athletic shoe incorporating a cushioning and gait-adapting device which provides resilient cushioning while adapting to the gait of the user during running and other athletic activities. The shoe comprises an upper and a sole with the sole having a heel with medial and lateral ground-engaging elements. A cushioning and energy return and gait-adapting device is provided and comprises a support structure and one or more spring devices. Each spring device has a generally U-shaped pivot or swivel section and lateral and medial resiliently flexible pods. The pivot section has a midportion which is supported by the pivot cradle of the support structure. Resilient flexing of the lateral pod responsive to weight-bearing forces causes reaction forces to be applied across to the medial pod which is then caused to flex so that the medial pod is brought into an orientation for contact with the ground.
