The Faction Skis Phaenom fs 01 90 is a versatile all-mountain freeski boot engineered for comfort and shock absorption. This model boasts a specialized liner for smaller feet, ensuring a precise and cozy fit. Its innovative hybrid cabrio / overlap design merges the close fit and edge control of an overlap boot with the progressive flex of a 3-piece construction. Paired with the patent-pending Phaenom strap, this boot offers rebound, shock absorption, and superior flex control. The strap's elasticity generates noticeable rebound during turns, enhancing power transmission, turn initiation precision, comfort, and predictability. Designed for customization, the boot comes with three interchangeable inserts (flip chips) that allow adjustable forward lean angles of 13, 15, and 17.
