The forward toe portion, the rear heel portion and said intermediate arch cushion portion are one-piece. The innersole being resilient. The innersole including a first flat bottom surface, a second upper surface having an intermediate arch portion whose contour is generally convex-shaped and a third concave-shaped surface extending from said bottom surface to said upper surface to define with said upper surface an arched projection extending upwardly from said bottom surface and outwardly at a distance about equal to or greater than the tangent of said toe radius edge and said heel radius edge. The arched projection defining a space beneath said third surface. The innersole permits said projection to resiliently deform into the space defined by said projection upon application of a load to said innersole to provide cushioning and/or support to an arch.
