Abstract:
An outsole for a footwear construction to provide added softness in the heel strike area of a foot while providing added stability to the outer edge of the outsole, comprises: a top layer contoured to the shape of a foot, thereby providing cradle support to the foot; and, a lower layer having a bottom most layer with a heel portion so constructed as to achieve different degrees of softness, the heel portion including a wedge-shaped piece positioned on the heel portion, positioned over the heel strike area and being of a softer durometer value material and having an outer edge of a harder durometer value material thereby providing added stability to the footwear construction and avoiding lateral collapsing. The top layer and bottom layer are cemented together, encapsulating the wedge-shaped piece in the footwear construction between the top layer and bottom most layer to form a stable walking platform for the footwear construction. The wedge shaped piece is apertured vertically, the number and size of the apertures in the wedge-shaped piece being larger than those in the outer edge area. The apertures in the wedge-shaped piece outer edge may be moon-shaped. A sock may be provided to cover the top contoured layer for added cushioning for a foot.
