Abstract
A shoe sole comprising a front sole portion passing over into a rear sole portion via an intermediate sole portion consists of an upper sole portion, being formed at the top surface of the sole facing the sole of the foot at least partially of wood or wood like materials, and of a lower sole portion connected with the bottom surface of the upper sole portion and consisting of an elastic material. The thickness of the lower sole portion within an area of the rear sole portion is, as measured in normal direction to the top surface of the sole, at least 1.5 times, preferably twice, the thickness of the lower sole portion within the area of the front sole portion. Furthermore, the thickness of the lower sole portion within the area of the rear sole portion is, as measured in normal direction to the top surface of the sole, at least one-third of the thickness of the upper sole portion within the area of the rear sole portion, the thickness of the lower sole portion within the area of the rear sole portion being conveniently at least the same, or is even greater, than is the thickness of the upper sole portion within the area of the rear sole portion. The lower sole portion has the properties of a running sole at least within the area of the rear sole portion and is applied to the upper sole portion by forming operation, preferably by foaming operation.
