ABSTRACT:
A boot-type of footwear device is equipped with springs which enable the user to experience a bouncing effect. Four coil springs disposed in a rectangular pattern are disposed upon the underside of the boot. The upper extremities of the springs are embedded in an anchoring base such as a monolithic plastic casting affixed to the underside of the boot. The lowermost extremities of the springs have a non-slip footing. By virtue of its specialized construction, the device provides a more controlled effect during use.
