  • Flexibility adjuster device, particularly for ski boots
    Patent number: 5067258
    Abstract: In a ski boot having at least one quarter associated with a shell, the adjuster device includes a locking means for selecting the mutual sliding between two flaps which can partially overlap one another and are provided rearward to the shell. The device therefore allows, by locking the sliding of the flaps in different positions, to limit the flexing of the quarter and therefore adjust the flexibility of the boot.
