  • Patent number: 4122900
    Abstract: A cushioned horseshoe with a lightweight, metal plate and a unitary resilient tread bonded to the entire adjacent surface of the plate and molded to form a raised toe calk, cushioned raised heel calks and raised, self-cleaning traction cleats disposed on a unitary resilient base. The shoe is designed for use on turf, fast track or mud track and for use on any one of the horse's hooves. Cushioning is provided directly to the critical heel area of the hoof by providing heel cushion holes in the heel areas of the plate to permit the heel calks to project through the plate and to resiliently engage the horse's hoof while still maintaining a rigid contact between the remainder of the hoof and the plate to permit the plate to be securely nailed to the hoof.
