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. Located in the medial lateral of the innersole is an arch protector. The Horizon Arch Guard ( 34 ) is made of cut out patterns of carbon fiber materials that are zigzag stitched and then dipped in a polymeric resin. The materials are shaped accordingly, left to harden, and then integrated into the formation of the innersole's arch development. This arch guard is a contoured slope wedge integrated within the formation of the innersole to form an upside down U-shape for a controlled varied rocking motion evenly distributing pressurized weight. To counter the weight of force exerted by impact, located under the innersole are 4 individual air chambers. These air compartments work in synchrony by pressure being applied. In the forefoot area is an Air Compression Compartment ( 22 ) where air is held until pressure causes the air to travel to the Forefoot Air Bubble ( 7 ). Pressurization to this area pushes air back into the Air Compression Compartment ( 22 ). This is the same for the Heel Air Compression Compartment ( 32 ) releasing air into the Heel Air Bubble ( 14 ) upon impact pressure. When weight is equal the air cushioning is evenly distributed over the impact zones, thus giving the wearer total independent stabilized air cushioning at a stand still.

Claims

exact text as granted — not AI-modified
1 . A technical innersole device to add cushioned protection to athletic footwear, comprising: 
 (a) of an underlying said foot contour shaped thermoplastic innersole with a said integrated thermoplastic cupped heel, 4 said individual extended foot pressure based implements with said flex grooves (b) and 4 said individual mechanized congruent workable interacting air compartments (c) also with a said carbon fiber cut out pattern with zigzag stitching, polymeric dipped and integration of said arch guard wrapping under the said development of innersole's arch development.
