A running shoe must have a yielding sole in order to protect the bones of the foot and the leg, especially when the foot touches the ground. In order to improve such running shoes, oblique, elastic ribs (1) are mounted between the binding sole (3) and the wearing sole (2) so that a bending of the ribs takes place when the foot touches the ground, by means of which energy is accumulated, which energy is released during the take-off by the straightening out of the ribs so that this energy can be utilized as a contribution to the energy of the foot. The ribs (1) have an angle (//c) of approximately 40` to the horizontal plane, and are oblique from the binding sole (3) forward against the wearing sole (2). The ribs (1) are dimensioned according to the required yielding and elasticity, the dimensions, number, and angle (//c) of the ribs corresponding to this. The ribs (1) are preferably made of polyurethane on the basis of ether, which produces good elastic qualities. Finally, ventilating apertures (12) can be arranged between the binding sole and the space between the ribs, so that air is pressed from the airspace upwards to the sole of the foot while running. |
