Abstract
Abstract An sole having an upper elastomer foam pad supported by an overexpanded honeycomb structure, the overexpanded honeycomb structure made by intermittently bonding ribbons of elastomer and expanding them laterally to produce a honeycomb structure having rectangular cells with the longer opposite walls of the rectangle twice the length of the shorter opposite walls of the rectangle, with the shorter opposite walls of the rectangle being double walls, and with the shorter opposite walls of the rectangle elongated in the direction across the sole.
