Abstract
A shock-absorbing athletic shoe system for cushioning impact forces includes an athletic shoe having a flexible impervious bladder positioned within the sole of the shoe. An external fluid-holding surge tank communicates by way of a fluid conduit with the bladder of each shoe. Quick release connectors are interactive between the lowermost extremities of the fluid conduits and the shoes.

A shock-absorbing athletic shoe system comprising:
- a) an athletic shoe having a sole, a heel portion having an exterior boundary, and a flexible impervious bladder positioned within said sole,
