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.
Claims6
A material for replacing the high wear regions in the heels of outdoor shoes wherein high density wear-resistant particles of substantially spherical shape and approximate mesh 8 to 16 are embedded in a two-component urethane binder having a hardness in excess of approximately 50 on the Shore D scale.
