A slide-piece (22) possessing a backward-projecting control (10) moves along the shoe's lengthwise direction and is positioned on a housing (13) in the rear underneath structure of the shoe. A tensioning lever (9) when depressed engages with the slide-piece and has, on its underside, a guide (37) for the top end of a rocker-arm (39). The tension-lever guide for the top end of the rocker arm in the form of a one-piece lever has two branches angled towards each other. The slide-piece has a stop face, while the rocker arm has an engaging element (41) engaging with the stop face. The slide-piece has a forward-open connecting-link guide with which the engaging element interacts. |
