Spring plate for athletic shoe midsole

Abstract

In general, one or more aspects of the disclosure relates to an athletic shoe comprising an upper and a sole. The sole further comprises an upper midsole, a lower midsole and a plate disposed between the upper midsole and the lower midsole. The plate comprises a toe region having a planar shape. The toe region is encapsulated between the upper midsole and the lower midsole. The plate additionally comprises a heel region having a contoured incurvature. The heel region protrudes externally from between the upper midsole and the lower midsole to form a sidewall that encompasses a heel region of the upper midsole. The unique combination of the two shapes of the plate provides comfort and stability as well as enhanced energy return in the heel with less force upon the heel of the wearer and with the sidewalls provides stability and then the planar forefoot shape placed between the two midsoles offers propulsion, at the metatarsal flex and toe area during the gait cycle.
