Abstract: A shoe heel shock absorber comprising a lower pedestal with a penetrating hole that penetrates through from a top surface to a bottom surface of the lower pedestal; a step edge is formed on an inner surface of the penetrating hole in the top surface of the lower pedestal; an air-cushion is fixed on the to surface of the lower pedestal, which comprises a straight hole and several second positioning holes which are through the air-cushion, and the second positioning holes correspond to the first positioning holes.

Abstract: Present invention provides a shock absorbing structure for the heel of high-heeled footwear, which comprises A Lower Pedestal with Penetrating Hole that penetrates through the Lower Pedestal's top surface to bottom surface. A Step Edge is formed on the inner surface of said Penetrating Hole in the end close to the top surface of said Lower Pedestal. An Air-Cushion is fixed on the top surface of said Lower Pedestal, which comprises a Straight Hole and several Second Positioning Holes winch are through said Air-Cushion. Said Straight Hole corresponds to said penetrating hole and said Second Positioning Holes correspond to the First Positioning Holes.

Abstract: The present invention is an improvement of the inner sole configuration of protective shoes, which is achieved mainly by disposing a rigid plastic inner sole plate on the shoe sole. The inner sole plate is made of an insulating rigid plastic material, forming a concavity for firmly contacting and comfortably supporting the wearer's foot sole. It also enlarges the margin areas preventing penetration. This inner rigid plastic sole plate includes three plate bodies connecting to one another and thereby is adapted to be upwardly bendable. Therefore, the present invention effectively improves the comfortable wear, safety, and good electric and thermal insulation of the protective shoes.
