Abstract
A shoe has a sole with an energy control system for shock absorption and for propulsion of the wearer. The energy control system includes a spring system and an overlying energy absorbing member located in a cavity in the midsole. The spring system includes a spring plate with a plurality of curved, resilient strips projecting there from. The resilient strips are deformed under the load of the foot of the wearer and then return to their original shape as the foot is lifted and the lead is removed. A support rib at the rear of each resilient strip directs the released energy in a forward force component as the strip returns to its uncompressed shape. An energy absorbing member, preferably a layer of urethane is provided over the spring system.
