  • Patent number: 4641438
    Abstract: An athletic shoe for running is disclosed. The shoe has a tread design of triangular faced, slope-sided, prism-shaped, canted studs arranged in a pattern which limits and controls impact forces conducted to the foot. A set of triangular, prism-shaped stabilizer pins molded laterally into and across the outersole protects the metatarsal bones and helps to propel the foot into the next step. Tetrahedral lateral heel stabilizers control lateral roll of the ankle area and pyramidal buttress supports at the stabilizer end reduce impact shock to the metatarsal area. An interior sole further reduces impact forces and an interior lining directs perspiration away from the foot.
