Abstract
A removable insole for insertion into footwear, includes a forefoot portion extending at least to metatarsals of a foot, the forefoot portion including a combination layer formed from a bottom layer of a resilient foam material which provides a shock absorption cushioning function, and a top layer of a slow recovery material which absorbs shear forces applied to the second layer at pressure points and spreads out the shear forces along the forefoot portion, the top layer being of substantially the same dimensions as the bottom layer and superposed therewith, the bottom and top layers having the same thickness and outer dimensions; a cupped heel portion formed by a relatively flat central portion and a sloped side wall; a mid-foot portion connecting together the forefoot portion and the heel portion, the mid-foot portion including a medial arch portion and being connected to the forefoot portion at the medial arch portion, the heel portion and mid-foot portion together being formed by a unitary layer of resilient material, and the sloped side wall extending around a periphery of the heel portion and forwardly to at least the mid-foot portion of the insole; and a top cover secured to upper surfaces of the forefoot portion, mid-foot portion and heel portion.
