Contoured Support Shoe Insole

Abstract

An insole having a top sheet, a base layer, a forefoot pad, a heel cushion, and support cushion, as well as a strength layer inserted between those components to strengthen and enhance the durability of the insole. The forefoot pad can be made a blown EVA or other material, and the heel cushion can be made of a clear TPR, soft polyurethane or blown EVA. The support cushion has a raised lateral arch and a raised medial arch, the later of which has longitudinal curvilinear indentations, a flattened central midfoot area with a metatarsal mid-foot tear-drop raised area and longitudinal ridges on the flat midfoot area. A heel cup surrounds the exterior back by a heel cup, and a heel pod opening goes through the entirety of the thickness of base layer of the insole body for placement of the heel pad so the heel pad is affixed to the bottom surface of the base layer. There is also a supersoft metatarsal raised dome on the top (foot contact) surface of the insole which would be directly above the metatarsal midfoot area.
