Ski boot (Machine-translation by Google Translate, not legally binding)

Ski boot, comprising a flexible boot (1), an exostructure (2) containing said flexible boot (1) and a sole (3), said ski boot forming a cane (4) to accommodate the ankle of a person and a shovel (5) for housing the foot of said person, and comprising a device for modifying the stiffness of the sole, adapted to reversibly change a state of rigidity of said sole (3), between a state of rigid sole and a non-rigid sole state, characterized in that said sole (3) is a flexible body free of joints, and because said device for modifying the stiffness of the sole comprises: - a stiffening structure which is fixed to said sole (3) and which is formed by several rigid parts (6, 7, 8) of said exostructure (2), said rigid parts (6, 7, 8) being related to each other so that they can experience a relative movement between them allowing a flexing of said sole (3), said stiffening structure being able to pass reversibly from a blocking state, in which said relative movement between the rigid parts (6, 7, 8) is blocked preventing the flexing of said sole (3), and an unlocked state in which said relative movement between the rigid parts (6, 7, 8) is unlocked allowing the flexing of said sole (3); - and an actuator (9) acting on said stiffening structure and being manually operable between a first position, wherein said actuator (9) blocks said relative movement between the rigid parts (6, 7, 8) thus maintaining said stiffener structure in said locking state, and a second position, wherein said actuator (9) unlocks said relative movement between the rigid parts (6, 7, 8) thereby putting said stiffening structure in said unlocked state.
