US Patent 6895695 Shoe structure

A shoe structure mainly includes a sole, a heel, and a vamp adapted to enclose at least part of a wearer's foot. A reinforcing plate is embedded in the sole to extend from a rear end to a near-middle point of the sole for bearing a downward force from a suspended rear half of the wearer's foot, and a cushion pad is connected to a lower end of the heel. The sole is provided on the rear end with a recess for receiving a fixing plate therein. A screw is extended through the fixing and the reinforcing plate into an internally threaded tube embedded in the heel, providing an enhanced connecting force between the sole and the heel and preventing the heel from breaking or separating from the sole.
