Abstract
A sole for a shoe, in particular for a running shoe, the sole having a polyurethane injected midsole, a longitudinally extending shank, and an outsole. The shank extends from the forefoot of the sole through an arch area to a heel area and has an opening in its heel area for receiving polyurethane during injection of the polyurethane for the midsole. Further, the shank has a cavity for receiving a comfort element. The heel area of the shank is offset to be closer to the outsole than the shank in the arch area. The sole provides a low weight sole while still providing comfort to the wearer of the shoe. By placing a comfort element in the cavity, in the heel area of the shank, which comfort element has a higher elasticity than the polyurethane of the midsole, the sole provides improved energy absorption and energy return.
