- and
- a plurality of resilient cleats having a truncated cone configuration fixed to the bottom surface of said cushioning pad and projecting therefrom to contact the running surface, at least a portion of said cleats tilting at an angle other than normal to said planar surface and towards the side edges of the pad thereby to facilitate compression of the cleats to increase the cushioning and stability of the foot during running.
