Abstract
An athletic shoe with a teardrop shaped spring plate in combination with a dynamic fluid heel pad and a viscoelastic midsole, such spring plate being basically symmetrical about its longitudinal axis, and lying forwardly of the fluid pad, having its widest dimension beneath the metatarsal head area and curving gradually up and beneath the phalanges. The spring plate, of multiple layers of parallel fibers embedded in polymer, combines with the heel pad to effect foot control stability, as well as extending useful life to the midsole and footwear.
