When it comes to technical features, supreme fit, and ultimate response, the Thraxis is a clear leader in the freeride category. The stiffest flexing and most supportive model in our collection, this snowboard boot is for 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 lined 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 provide a more "quiet" 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.
H4 FOCUS BOA® FIT SYSTEM:
Impact-resistant, durable, and performance-driven, the H4 BOA® Dial ejects on severe impact and is easily re-inserted into the boot. One dial controls the upper shell lacing, and the other maintains the lower shell lacing.
CONDA™ BOA® LINER LACING:
Proprietary liner lacing system that harnesses the power of BOA® to provide superior heel hold and support.
INTUITION® SPACEHEATER™ LINER:
A liner designed for comfort and warmth, from start to finish. It features reflective heat blanket panels that work to trap heat in and keep cold out. These reflective heat blankets work alongside heat moldable Intuition® foam, internal J-Bars, and 3D molded, dual- density EVA insoles to keep your foot comfortable and warm all day long.
FLEX ZONE UPPER CUFF:
The flex zone upper is designed to help retain a consistent flex pattern while reducing shell distortion when flexing.
ENDO™ 2.0 CONSTRUCTION:
A K2 Snowboarding exclusive, Endo™ Construction, allows us to alter a snowboard boot's flex, response, and rebound without adding extra materials (extra materials = excess weight). By replacing additional materials with an injected heel counter, adding an extra rebound is as easy as a formula change. In addition, it helps us to provide a more consistent flexing, longer-lasting snowboard boot.
HARSHMELLOW™ VIBRATION DAMPING:
Harshmellow™ is a magical dampening system that replaces industry-standard foam dampening materials. Harshmellow™ is strategically placed to dampen vibration underfoot to provide a more “quiet” feel underfoot, reduce vibration from impact, and reduce fatigue while snowboarding.
3D FORMED DUAL DENSITY EVA FOOTBED:
Dual-density EVA foam provides contouring cushioning and support to support snowboarding all day long.
