Abstract
Footwear includes a high modulus moderator located between the wearer's foot and cushioning material above the foot in which the moderator is a relatively thin, lightweight material having a modulus of elasticity of at least about 250,000 psi. The heel moderator includes medial and lateral legs positioned to be located under the calcaneus of the foot with the cushioning located beneath the moderator such that a cushioning medium is located below the calcaneus. The moderator, which deflects without permanent deformation and includes portions extending upwardly, operates to absorb, redistribute and sore the energy of localized loads. A moderator may also be located under the forefoot, as described.
