Product details

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 “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.

The boots fit comfortably and snugly, without feeling too tight or constricting. I appreciate the durable construction of the boots, as they have held up well against the rough terrain on the mountain. In terms of performance, the K2 Thraxis boots do not disappoint. They provide excellent support and control while riding, and have helped me improve my skills on the mountain.

One downside of the K2 Thraxis boots is the price point, which is on the higher end compared to some other options on the market. Additionally, the color options are somewhat limited, so if you're looking for a specific shade, you may have to look elsewhere. Finally, the boots are on the heavier side, which can be a drawback for some riders.

Overall, I would highly recommend the K2 Thraxis snowboard boots to any rider looking for a high-quality, comfortable, and performance-driven boot.

  • Comfortable fit
  • Durable construction
  • Excellent performance
  • Limited color options
