Shoe having improved impact cushioning and shock absorption

摘要

Improved impact cushioning within a shoe is provided by a novel heel hammock recess formed beneath the heel of the wearer. The heel hammock recess includes an elastic member supporting the wearer's heel surrounded by a surround surface formed to bear substantial weight. The impact energy transmitted upwardly through the heel to the wearer's foot during heel impact passes through the elastic membrane of the heel hammock allowing flexing and energy absorption to occur as the heel is cradled in the heel hammock. Embodiments are shown in which the impact absorbing member is formed integrally with a molded athletic shoe sole as well as alternative embodiments in which the impact absorbing structure is formed in a removable insole and also formed in a variety of general use shoes.
