Abstract
Abstract A substantially flexible unitary wedge-shaped unit sole for high heeled shoes is disclosed contoured with compound curves in the side bottom surfaces thereof to enhance the comfort and stability of the wearer while at rest, and further to enhance the stride during walking. In addition, the sole is constructed to provide the stable feed of a solid wedge while being substantially hollow to reduce the weight thereof, and to provide a deliberately placed flexibility during walking.
