K2 Men's Thraxis Snowboard Boots 2027

When it comes to technical features, supreme fit, and ultimate response, the Thraxis is a clear leader in the freeride category. It’s 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 fit 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 our Eco-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 Vibram® V5 outsole, providing unmatched traction in the boot pack and is made using at least 30% recycled rubber through the Vibram® Ecostep program.  BOA® Zonal Fit System Powered by H5 The dual-dial Zonal BOA® configuration delivers a micro-adjustable, multi-directional, zonal precision fit. Upper and lower lacing is controlled independently, providing the most precise fit throughout the boot. The BOA® Fit System is engineered and guaranteed to perform in the toughest conditions. TX3 BOA® Lace The best of both worlds. TX3 is a flexible and low-friction textile lace used on snowboard boots to provide a soft, modern design aesthetic with lasting durability and strength. S’Cafe™ Coffee Mesh A coffee ground mesh liner layer that controls odor and absorbs moisture. Intuition® Pro Foam 3D Liner with Spaceheater™ A premium and heat-moldable liner built with Intuition® foam and lined with breathable heat-reflective SpaceHeater™ technology for superior warmth and comfort. Internal & External J-Bars Adding J-Bars to a liner helps add structure and reduce heel lift. Eco-Harshmellow™ Pro Insole Three separate compositions, Pro, Plus, and Base, now all incorporate K2’s proprietary Harshmellow™ damping into the layup of the footbed. The result is superior vibration absorbing and comfort for all-day excursions into the backcountry or hiking and riding around the resort. Vibram® V5 Outsole with Eco-Harshmellow™ Our premium rubber compound provides industry-leading durability and grip and is integrated with Harshmellow™ foam to absorb chatter and vibration. 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. Rubber Reinforced Flex Zone Upper A small flexible notch at the boot's instep allows for a smooth forward flex with minimal shell distortion. Abrasion resistant reinforced outsole rubber is placed in areas of high stress to extend the life of the boot and increase durability.
