Abstract (en)

An outer sole for footwear is provided with one or more impact-damping and grip-improving means. The sole can for instance have a damping cavity which is provided under the forefoot portion, and in particular under the ball section portion, of the sole. Furthermore, the outer sole can be provided with means for increasing the grip of the sole, which means is provided on the lower side of the sole on the transition from the foot cavity portion of the sole to the ball section portion of the sole. The outer sole can also be provided with a damping cavity which is formed under the heel portion of the sole, which heel damping portion has in that direction side walls which taper towards each other, which side walls, in the presence of a downward loading force, deform in horizontal direction to absorb impact forces, and with almost vertical slots with almost vertical walls, which are present in the side walls with their longitudinal direction in the circumferential direction of the heel damping cavity. Finally, the outer sole can be provided with a forefoot portion, a heel portion and an intermediate hollow shank portion which, upon placement of the sole on a horizontal surface, forms a bridge and does not contact the surface, and with ridges which are formed substantially transverse to the longitudinal direction of the sole under the bridge and which extend in a position of rest slantingly from the bridge and are resiliently bendable from the position of rest into a position located nearer the bridge. <IMAGE>
