Abstract

See full text

An impact absorbing footwear device employs opposed planar sole portions engaged by a selective resistance coupling that biases the opposed planar sole portions in a non-linear manner in response to forces exerted by the wearer against the sole portion in frictional contact with a floor surface. The planar sole portions are disposed in a footwear appliance that takes the form of an athletic shoe sole. The selective resistance coupling includes a plurality of resilient deformation members that engage the planar sole portions in an opposed circumferentially aligned manner, selectively deform in response to pressure exerted by the wearer for preventing ACL and other impact related injuries, and recover to an undeformed rest position without breakaway to allow the wearer uninterrupted usage while dampening forces that surpass an injury threshold from the resilient deformation that allows the planar sole portions to temporarily misalign.
