When it comes to technical features, supreme fit, and ultimate response, the Thraxis is a clear leader in the freeride category. Its the stiffest flexing and most supportive model in our collection, this snowboard boot services even the most demanding of riders.

The Thraxis’ Zonal BOA Fit System features three BOA dials, two targeting zonal exterior lacing, and one controlled K2’s Conda liner lacing system. By placing a soft, urethane “chip” around the 45 degree of the ankle, we’ve allowed riders to micro-adjust their boot fit and eliminate heel lift. Wrapping the foot, we’ve placed our most supportive liner, composed of multiple densities of heat-moldable Intuition foam. This open-cell foam means that it can be re-molded time and time again to achieve the perfect fit throughout the boot’s life. The liner is outfitted with our breathable and heat reflecting Spaceheater material, keeping riders warm and dry all day long. And lastly, we’ve integrated a 95% post-consumer recycled coffee mesh from SCafe into the liner to help eliminate unwanted odor after a long day on the hill. Underfoot, the midsole combines a lightweight and stable EVA and Harshmellow, a proprietary technology that helps absorb impact, increase damping, and provides a quieter feel while snowboarding.

The outsole on the Thraxis snowboard boot is our ALL-NEW Vibram V5 outsole, providing unmatched traction in the boot pack and is made using at least 30% recycled rubber through the Vibram Ecostep program.
