The K2 FL3X Revolve KF Ski Boots are the launch pad for Karl Fostvedt’s signature send—it’s full throttle or nothing.
The K2 FL3X Revolve KF Ski Boots are the launch pad for Karl Fostvedt’s signature send—it’s full throttle or nothing. With an updated even beefier flex of 130, and a comfy Intuition Pro Wrap liner, they’re built to handle high-speed pillow drops, sketchy landings, and rowdy side hits like it’s just another day at the office. If your idea of fun is turning natural features into a playground and going all out, these boots are your ride-or-die.
Last: 99mm – A slightly narrower than average fit for most feet.
Flex: 130 – A very stiff flex for advanced to expert skiers.
Intuition Pro Wrap Liner – Slip into the Intuition Pro Wrap, and experience unmatched ankle retention and pressure-free performance. Crafted out of Intuition® Foam, the Intuition Pro Wrap offers the added comfort and performance your boot is missing.
Shell – TPU (Thermoplastic Urethane)
Cuff – TPU (Thermoplastic Urethane)
Revolve Plus Shell – The Revolve Plus Shell takes the same 99mm last and opens up the toe box for a roomier feel out of the box. The Pillar Shell uses the original 3-piece design and adds replaceable soles for extended longevity and increased traction.
Fully Heat Moldable – Both the boot's shell and cuff are capable of being heat molded to a variety of foot shapes for a truly custom fit.
3 Revolve Alloy
Elastic Cam Strap - One Piece – Increases performance and responsiveness by cinching tighter than a traditional power strap resulting in exceptional power transmission and precise handling.
GripWalk ISO 23223 Outsoles – Removable and interchangeable rockered soles designed to work with GripWalk binding systems for better grip and comfort while walking, standing, and hiking.
