  • Durable material for outdoor shoe heels
    Patent number: 5276981
    Abstract: A very long wearing material to replace regions that erode rapidly in the heels of outdoor shoes. The material is made by embedding relatively large, round, wear-resistant particles in a very hard urethane binder. Applications include both applying the material directly to the heel as a paste with curing in situ and casting in molds for attachment to the heel with an adhesive.
