ABSTRACT:
A hydrodynamic pad including fluid-filled inner and outer bladders interconnected by fluid channels and configured such that displacement of fluid from the center of pressure distribution generated by foot impact radiates from the inner bladder outwardly to the outer bladder through one or more of the fluid channels causing the outer bladder to expand to an expanded condition. The expanded outer bladder seats the wearer's heel in the hydrodynamic pad, thereby stabilizing the foot of the wearer, and the controlled flow of fluid through the fluid channels to the outer bladder dissipates the impact loads, thereby cushioning the wearer's heel. When the pressure is released from the inner bladder, by lifting the wearer's heel, the expanded outer bladder forces at least a portion of the displaced fluid to the inner bladder, such that the hydrodynamic pad is reinitialized.
