Footwear with energy storing sole construction

摘要

A sole is adapted for use with an article of footwear to be worn on the foot of a person while the person traverses along a support surface. This sole is operative to store and release energy resulting from compressive forces generated by the person's weight on the support surface. The sole is thus an improvement which can be incorporated with standard footwear uppers. Alternatively, the invention can be configured as an insert sole which can be inserted into an existing shoe and other article of footwear.
