ABSTRACT A pair of running shoes, each having an upper and a sole. The sole runs the length of the shoe from the heel to the toe and com- prises an outsole and a midsole, the midsole including a first member and a second member, each member being a variable thickness across the width thereof. The first member is disposed above the second member so that the combined thickness of the members is constant across the width of the sole. Each of the members is formed of a material having a different durometer, so that the ratio of the thickness of the higher durometer material relative to the lower durometer material is greatest immediately adjacent the inner side of the sole and is lowest immediately adjacent the outer side. This construction permits greater contact surface area than conventional shoes, thereby distributing impact shock more evenly during running, yet providing medialongitudinal arch support for decreasing abnormal pronation, while allowing for the natural pronation of the foot.
