Abstract
The present invention provides a composite shoe bottom that has a lower shaped support layer with a lower surface and an increased height around the periphery of the heel area and an irregular contoured upper stabilizing surface for the wearer's foot; a shoe upper superimposed upon the upper surface of the lower layer; an upper cushioning layer of a material that is softer than the lower layer, the upper layer having a varying thickness which is pre-shaped to a contour complementary to the bottom surface of the wearer's foot and having an increased height around the periphery of the heel area and in the arch area to form a raised arch support and to provide an irregular contoured upper stabilizing surface for the wearer's foot; and means for forming an outsole secured to at least a portion of the lower surface of the lower support layer and comprising at least one strip of a wear resistant material which is positioned upon the lower layer in an area which will experience abrasion or shock.
