As soon as one of the two inclined boundary surfaces 7d, 7e of the control element 7 has reached or exceeded the control nose 4d begins, the control member 7 is pivoted up and takes the pawl lever 14 against the force of the leg spring 13. As a result, the tab bolt 16 is released from the horizontal lever arm 14a of the ratchet lever 14, and the sole holder 6 swivels up under the action of the shoe.
