Abstract: This invention relates to an improved design associated with the fabrication and construction of an athletic shoe sole capable of minimizing stress and strain to the functioning portions of the human body associated with any athletic endeavor that utilizes an individual's lower extremities to participate in same. In accordance with the invention, there is created an athletic shoe sole that permits the mirroring as well as the complementing of the natural bend of the human foot at the metatarso-phalangeal joints in that the composition and construction of said athletic shoe sole coincident with its location at said metatarso-phalangeal joints varies from the overall composition of said athletic shoe sole so as to evidence compression and expansion characteristics different from that of the overall characteristics of the composition of material utilized in fabricating said athletic shoe sole thereby achieving the overall advantages of the invention.
