Abstract: A ski boot is provided having a clamping device mounted on the rear heel part for tightening and loosening a mechanical coupling arrangement connected to a restraining part arranged on the ski boot. The clamping device may be a hydraulic, pneumatic or electric driving system with an adjusting element for acting on the mechanical coupling arrangement. At least one actuating element is mounted on the top side of the clamping device, which can be depressed with the help of a ski pole so as to permit clamping of the retaining part with the desired tightness.
