ABSTRACT:
A lightweight sole construction to be secured beneath a shoe for comfortable stride amplification by absorbing and releasing a user's impact energy. The invention accomplishes this by providing three primary elements which emulate, in sequence, the three basic movements of a forwardly moving foot in contact with the ground which are; heel impact, roll-over, and metatarsal thrust. A hinged leaf spring, having a pair of hinged leaves sandwiched in the heel area of a frame, absorbs energy by tensioning a group of ringed elastics as it's lower curved ends separate. An x-shaped leaf spring, being sandwiched in the toe area between a top and base plate, engages and emulates the user's metatarsal thrust by having free ends which slide apart when depressed and stretch a group of ringed elastics while pivoting about a central axis. A z-shaped platform houses and aligns the spring devices while providing a central support for the user's weight to roll-over. The device affords comfort to the user by employing spring mechanisms that inherently resist unwanted movements such as sidesway, and which are easily adjustable.
