Abstract
A shoe structure for foot strike energy dissipation employs compressible members each having an internal void containing a first working fluid. A set of mating compressible members are each connected to a related one of the first compressible members through a fluid conduit such that the first working fluid is transferred from the related compressible member to the mating compressible member responsive to compression induced by foot strike. Resilient structural members are placed intermediate the compressible members to deform responsive to compression of the foot bed induced by foot strike provide both energy dissipation and resilient recovery of the compression cylinders to their uncompressed state. A cavity contains a second working fluid that is transmissible between the compressible members responsive to compression of the foot bed. Cooling tubes are provided for energy dissipation of the second working fluid which bathes the compressible members, conduits and resilient elements.
