Abstract
A composite midsole for shoes comprising an energy absorbing cellular foam cushion having recesses extending inwardly from its undersurface, thermally bonded to a sheet of resilient material extending over the undersurface and into the recesses to form domes of the resilient material. Impact energy is partially absorbed by compression of the cushion and partially transmitted to cause spring-like deflection of the domes. The combined effect is selectively variable over the area of the midsole to produce the desired cushioning properties in localized areas of the midsole.
