ABSTRACT:
A shoe is provided with a spring mechanism in the heel area. The spring includes a pair of generally circular end portions which are supported by the outsole and a beam portion which extends between the end portions. Initial impact cushioning is provided by resilient deflection of the end portions and compression of surrounding materials. The main cushioning is provided by linear deflection of the beam portion. Overload protection is provided by restorable collapsing of the cross section of the beam.
