ABSTRACT:
A ski boot structure in which the front cuff of the upper is intended to constitute the reference element ensuring all the functions related to the flexion control of said upper in cooperation with rigid extensions of the shell base and the closure device of the upper on the lower part of the skier's leg in skiing position. On the one hand, the front cuff includes abutments located opposite the abutments obtained on the extensions in the upper zone of the upper, and on the other hand, in the lower portion where it is extended by fastening hooks, an elastic element mounted in tension state to act in the front-to-rear direction. The closure device mutually connects the front cuff and rear spoiler on the inserted extensions while thus allowing the frontward flexion of the front cuff, and therefore of the upper, against the resistance of the elastic element without biasing said extensions and while rearwardly blocking said upper by means of the abutments of the cuff against those of the extensions.
