The K2 FL3X Revolve Pro Ski Boots are a tremendous choice for riders who have an equal affinity for freeride and park skiing, with a moderate 100 flex, K2's famed smooth-flexing 3-piece design, and an Intuition Pro Wrap liner. Essentially the same boot as the Wallisch Pro model without the GripWalk soles, Cam strap and splashy colorway, the Revolve Pro is the choice for freestyle-oriented skiers who intend to make a name for themselves.
