发明名称 Heels for footwear
摘要 A heel for footwear includes a resilient, compressible generally wedge-shaped insert which is secured between a ground-engaging part and an upper part of the heel and absorbs shock. The insert tapers in depth away from the back of the heel while the rear end of the ground-engaging part of the heel slopes upwardly towards the back of the heel to reduce wear at the back of the heel.
