Abstract
An athletic shoe having a hydrodynamic heel insert pad in the midsole to above a specially configurated spring plate which extends beneath the medial but not the lateral portion of the heel, through the arch region, to and beneath the metatarsal head region and toe region, serving to eliminate the force spike at heel impact in combination with foot control as the foot proceeds via complex movements through the gait cycle, and efficient toe off.
