Abstract: A shaped interior stiffener is molded into a polymeric material pad, forming a cushioning pad that can be affixed to a stabilizer leg foot on mobile equipment such as a crane or excavator. A variety of foot pads is contemplated, each specifically designed to fit without alteration to a variety of different manufacturer's equipment through use of bolts protruding from one surface of the foot pad. The interior stiffener is shaped in such a manner that it conforms to the bolt pattern of a particular equipment model, having socket-like receivers for the heads of the protruding bolts, efficiently distributes stress throughout the structure to minimize stress failures, and provides a plurality of ribs, webs and openings to allow maximum durability and adhesion between the stiffener and the polymeric foot pad material which encapsulates the stiffener.
