The characteristic of this ski-boot consists in the fact that its back part is fixed to the boot-vamp by means of four links which form - together with the ski-boot (the fixed and the moving part) - two side-parallelograms. Such parallelograms allow the back part to near the front part whenever their links make half-rotation movement. This movement makes the final clamping push the foot forward by means of a slanting pressure caused by the palm of the hand. |
