摘要

The sole (1), designed to be fitted to a footwear upper (3), is made from a compressible elastic material and has a rear extension (5) sandwiched between upper (7) and lower (8) rigid components to form the heel (2). The rear extension is in the shape of a bayonet joint, forming a stepped upper recess (E) to receive the upper rigid component so that its upper surface (15) lies flush with the sole's upper surface (14).
