Abstract
A Reactive Energy Fluid Filled Toroid Apparatus includes concentric fluid filled toroids that are contained in the midsole of a shoe. The toroid apparatus provides cushioning for the foot and dynamically reacts to off-center impacts from footsteps to redistribute impact forces and to stabilize and support the foot by cradling a portion of the foot in the shoe.
