<p>A shoe heel insert (10), providing for superior shock absorption, energy return, and a high degree of stability. The insert (10) consists of a substantially heel-shaped outer spring mechanism (10) serving as an internal spring housing having a plurality of internally molded apertures (10f) engaging with a plurality of vertically affixed compression springs (14) retained within and biasing against outer spring mechanism (10). The entire unit filled with a pressurized gas and hermetically sealed with a clear, durable polyurethane material (12) which completely encapsulates the device allowing inner springs (14) to be visible and functional. The assembled unit fixably attached within the molded heel section of the mid-sole (4) of any type of footwear. The internal spring members (14) will be disposed directly below the calcaneus of the wearer and the transparent nature of the devices encapsulation (12) will allow the rear part of the shoe's mid-sole (4) to be molded in such a way that the system can be partially exposed.</p> |
