ABSTRACT:
Athletic footwear has an upper and sole. The sole has heel and midfoot regions and metatarsel and toe regions which include a foundation layer of semi-flexible material attached to the upper and defining a plurality of stretch chambers, a stretch layer attached to the foundation layer and having portions of elastic stretchable material underlying the stretch chambers of the foundation layer, and a thrustor layer attached to the stretch layer and having portions of stiff material underlying and aligned with the stretch chambers of the foundation layer and with the portions of the stretch layer disposed between the thrustor layer and foundation layer such that interactions can occur between the foundation layer, stretch layer and thrustor layer in response to compressive forces applied thereto upon contact of the heel and midfoot regions and metatarsel and toe regions of the sole with a support surface so as to convert and temporarily store energy applied to heel and midfoot regions and metatarsel and toe regions of the sole by a wearer's foot into mechanical stretching of the portions of the stretch layer into the stretch chambers. The stored applied energy is thereafter retrieved in the form of rebound of the stretched portions of the stretch layer and portions of the thrustor layer therewith.
