  • Shoe heel structure for a woman's shoe
    Patent number: 4424635
    Abstract: A shoe heel, particularly for a woman's shoe, has a body with a small cross-sectional end area and a wear piece or heelpiece of an abrasion-resistant material. The body and wear piece are connected by a pair of telescoping tubes having non-circular cross-sectional shapes, one of which is embedded in the body during molding thereof, and the lower end of the other is embedded in the wear piece. The tubes have aligned slots with material exposed to increase the frictional engagement for holding them together.
