K2 Thraxis Snowboard Boot 2026
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 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.
H4 COILER BOA® FIT SYSTEM WITH TX3 LACING:
A cable and reel based lacing system that creates even tension and easy lacing operation. This system features low friction guides for even tightening.
TX3 is constructed from recycled PET with a structural core. This lace provices a softer, more flexible look similar to the characteristics of a traditional lace but the superior closure of a BOA® system.
FLEX ZONE UPPER CUFF:
The flex zone upper is designed to help retain a consistent flex pattern while reducing shell distortion when flexing.
RUBBER REINFORCEMENT:
Abrasion resistant reinforced outsole rubber is placed in areas of high stress to extend the life of the boot and increase durability.
ENDO™ 2.0 HEEL COUNTER:
An injected heel counter offers us the ability to provide a lighter weight snowboard boot with more precise rebound, and a longer life-cycle.
INTUITION® PRO FOAM 3D LINER WITH SPACEHEATER™:
Our most supportive liner, featuring a high-density Intuition® foam for added support and lined with breathable heat-reflective SpaceHeater™ technology for superior warmth and comfort.
INTERNAL & EXTERNAL J-BARS WITH CORED ANKLE POCKETS:
Adding J-Bars to a liner helps add structure and reduce heel lift, while coring liners out around the ankle bones reduces pressure points in sensitive regions.
S’CAFE™ COFFEE MESH:
BOA® CONDA™ LINER LACING:
HARSHMELLOW™ PRO INSOLE:
