Abstract A pair of running shoes. Each shoe includes an upper portion having an inner side and an outer side and a sole running the length of the shoe from the heel to the toe between the inner and outer sides of the upper portion. The sole is formed of a resilient material and comprises a wedge portion extending from the heel to a point beyond the arch of the wearer's foot and immediately to the rear of the first metatarsal head of the foot. The wedge portion is canted upward in the transverse direction from the outer side of the shoe to the inner side of the shoe so that during running a substantial portion of the sole makes contact with the ground during each step. The sole is constructed to be thicker at portions adjacent to heel than at portions adjacent to toe and is formed of an outsole, a midsole and an intermediate bevelled section disposed therebetween at the heel. The transverse wedge portion of the sole is formed by the midsole.
A pair of running shoes, each of said shoes comprising an upper portion and a sole, said upper portion having an inner side and an outer side, said sole running the length of the shoe from the heel to the toe between the inner and outer sides, said sole being formed of a resilient material and comprising a wedge portion extending the full length of the heel to a point to the front of the arch of the wearer's foot and immediately to the rear of the first metatarsal head thereof, said wedge portion being canted upward in the transverse direction from the outer side of the shoe to the inner side of the shoe along the length of said wedge portion, so that when the wearer runs in said shoes a substantial portion of each sole makes contact with the ground during each step.
