K2 Thraxis 2027 Boots de snowboard

Maximum support, precise hold

The Thraxis is the boot for snowboarders who want maximum support and direct power transfer, with a flex that's as stiff as it gets. Two BOA dials on the shell control the upper and lower zones separately, so you can fine-tune the fit around the shaft and forefoot independently. The upper H5 dial ejects on a hard impact and pops straight back in. A third dial runs the liner lacing, which uses BOA power to lock your heel in and give your foot extra support.

Built to last, built to stay smooth
Endo construction swaps bulky material for an injected urethane heel counter. The result is a lighter boot with strong rebound and a longer life. Rubber reinforcement in high-wear and flex zones keeps the upper tough, while Endo 2.0 keeps the flex consistent over the years. Inside, the heat-mouldable Intuition liner with breathable, heat-reflective SpaceHeater lining keeps you warm and comfortable. The Vibram V5 outsole delivers strong grip and durability, and its integrated Eco-Harshmellow foam soaks up chatter and vibration.
