ABSTRACT:
A ski boot including an upper journalled around a transverse axis on a rigid shell base. Also provided is an apparatus for determining the advancement angle of the upper, that is the angle which the upper forms with a vertical axis when at rest. In addition, the boot is adapted to flex forward from this advancement angle during skiing. The apparatus determining the advancement angle also determines the resistance moment of the boot to forward flexion from the advancement angle. This apparatus is an elastic apparatus integral with the shell base and the upper and extending between these two boot portions. The point of connection between the elastic apparatus and one of the two boot portions is adjustable between four positions. As a result, the length of the lever arm of the resistance moment of the boot can be varied by changing the point of connection of the elastic apparatus with one of these boot portions between these four positions, thereby providing a large number of different values for the rigidity of the boot.
