The fs 01 90 is the all-mountain freeski boot designed to achieve comfort and shock absorption. This model features a liner specifically designed for smaller feet, ensuring a precise and comfortable fit. The innovative hybrid cabrio / overlap construction combines the best of both worlds: the close fit and edge control of the overlap, and the progressive flex of the 3-piece. Paired with the patent-pending phenom strap, the fs 01 90 provides rebound, shock absorption, and exceptional flex control. The elasticity of the strap generates tangible rebound through your turns, for increased power transmission, turn initiation precision, comfort and predictability. Designed for customization, the boot comes with three different inserts (flip chips) that allow forward lean angles of 13°, 15°, and 17°. The sleek all-black design supports restoration and reuse of the boot and its parts. Each element of this product — from panels to buckles to straps and screws — is designed to be repairable and recyclable.
