ABSTRACT:
An adjustable shoe heel spring and stabilizer device provides the wearer of a shoe the ability to adjust the energy absorption and return characteristics of the shoe to suit their particular needs. An operable adjustment device is located on an exterior surface of the shoe. The wearer operates the adjustment device to selectively position a fulcrum at a desired location relative to upper and lower members of a spring mechanism disposed within the mid-sole of the shoe. The position of the fulcrum defines the energy absorption and return characteristics for the shoe. An indicator is provided for displaying to the wearer the relative position of the fulcrum, and hence the energy absorption and return setting for the shoe.
