Abstract
A reactive energy apparatus providing a custom fit and ankle support in a shoe upper is comprised of a pair of fluid filled pads that are positioned in the upper on opposite sides of the Achilles tendon of the wearer. The fluid filled pads each contain one or more interior chambers containing fluid, and the pads are connected in fluid communication by a series of conduits extending between the pads and around the Achilles tendon of the wearer. The conduits are constructed to enable the free flow of fluid between the two pads, enabling the apparatus to provide a continuous custom fit and dynamic support for the wearer's ankle while avoiding exerting any pressure on the Achilles tendon of the wearer that could potentially injure the tendon.
