THE FS 01 100 2025
The All-Mountain Freeski Boot Designed to Achieve Flex Perfection
The FS 01 100 is the all-mountain freeski boot designed to achieve flex perfection, power transmission, and shock absorption. The FS 01 100 is designed for those seeking both comfort and performance. It offers a more forgiving yet responsive feel.
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 Phaenom Strap, the FS 01 100 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.
