Foot cushioning device

Claim 1

A foot cushioning device designed in view of the physiological and kinetic considerations of the foot comprising: (a) a resilient body member having a medial side, a lateral side, bottom and rear walls defining a recess conforming to generally at least the os calcis portion of the foot, said rear wall adapted to extend along the plantar posterior portion of the heel to at least a location corresponding approximately to the vertical terminus of the os calcis; (b) resilient shock absorbing means extending from the outer surface of said body member from a first end on the posterior plantar portion of the rear wall to the second end at a location on the bottom wall of said body member, said shock absorbing means having the greatest depth in the heel strike area and tapering to said bottom and rear walls at said first and second ends, said shock absorbing means further extending from said body at said lateral and medial side walls whereby forces imposed by heel strikes are absorbed by deflection and deformation and antipronatory motion is induced to relieve stresses placed on the foot and leg by deflection of said shock absorbing means and whereby upon release of said shock from said shock absorber means returns substantially to its normal position.
