Estimating the term…
A triple density replacement insole which has at least two coextensive layers of different densities which are adjacent one another and extending the length of the insole comprising a first top cloth layer and a second gel layer and a third density layer comprising a stability cradle adjacent the gel layer. In a preferred embodiment, the stability cradle, which extends from the arch area to the heel area and secures to the gel layer, defines a first metatarsal region gap which exposes the gel layer and a second heel region gap which exposes the gel layer. A heel cushion is positioned in the second heel region gap adjacent to the gel layer and is secured to the gel layer exposed in that region. A metatarsal arch support is integrally formed in the first metatarsal region gap area.

A replacement insole, comprising:
The insole of claim 1 wherein said first appendage and fourth appendage control pronation and supination on the lateral side of the insole.
The insole of claim 1, further comprising a top cloth layer coextensive with said gel layer and secured to the top side of said gel layer.
The insole of claim 1 further comprising an advanced cushioning area integrally formed in said gel layer and located in a toe area along said bottom side.
The insole of claim 1, wherein the third measure of hardness of the heel cushion is softer than said first measure of hardness of the gel layer.
The insole of claim 1, wherein said heel cushion integrally forms a honeycomb pattern.
The insole of claim 1, further comprising a metatarsal arch support integrally formed in said gel layer and located in said metatarsal region, said metatarsal arch support extending dimensionally upwardly so that the metatarsal arch support extends out above the top side of said gel layer and forms a cavity in the bottom side of said gel layer.
The insole of claim 1, wherein said gel layer is selected from thermoplastic polyurethane elastomer (“TPU”) gel and thermoplastic rubber gel (“TPR”) gel.
The insole of claim 1, wherein said stability cradle comprises a thermoplastic elastomer gel having characteristics which provide rigidity to the area of the insole in which the stability cradle is secured.
