Abstract
The present invention comprises an intermediate layer for a shoe sole consisting of a hollow shell having convolutions disposed along the periphery thereof. The convolutions are adapted to cushion the foot by compressing when force is applied thereto, and expanding to their original configuration when the force is relieved. An inner filler material may be provided within the shell for added cushioning and resilience.
