Abstract: The 4-E.V.A System consists of an articulated 4-E.V.A. Innersole (35) contoured to the bottom of the foot. The heel of the foot is held in place by a pre-molded Thermoplastic Heel Cup (40) to keep the heel in a positioned alignment. This portion of the innersole is more sturdy and rigid to keep the lateral, medial, and back of heel in a more stabilized position, helping with injury prevention. Directly under the bottom of the innersole are 4 Pressure Impressions (36) (37) (38) (39) each separated by flexible grooves. These impressions are prestigiously placed based on the impact zones of the sole of the foot.
