ABSTRACT:
Ski boot comprising an articulated shank equipped with means of connection to the lower part, which means of connection make it possible to fix or release the shank for rotation, to regulate the inclination of the shank and the elasticity of an elastic element. The connection is supplied by a threaded bar (4) capable of being driven to rotate by a knurled wheel (14). The locking of the shank (5) in rotation is ensured by a lock (6). The elastic element is formed by a cylindrical sleeve (17) whose expansion is more or less inhibited by a sliding rigid sleeve (22).
