Abstract
A running shoe having an improved sole including one or more cushioning elements disposed at or around one or more of the foot's tripod strike points, wherein such cushioning elements may optionally be connected to each other by one or more bridges and the region bounded by the cushioning elements is vertically enlarged to provide added space for various structures of the foot to deform.
Claims16
An article of footwear comprising:
- an upper;
- a sole having a triangular shaped sole insert, wherein the triangular shaped sole insert includes:
- a heel tripod strike point enhancing, impact absorbing and recoil element;
- a first metatarsal tripod strike point enhancing, impact absorbing and recoil element;
- a fifth metatarsal tripod strike point enhancing, impact absorbing and recoil element;
