K2 Thraxis 2023 Snowboard Boots

The absolute performance boot, with an incredible amount of customisation options from K2 

Designed for those extra demanding days on the mountain, the K2 Thraxis is one of the most reliable and customisable boots in K2's product line. It's packed with premium features like the heat-reflective Intuition® SpaceHeater™ liner, a rubber-reinforced upper and three BOA® cogs for an ultra-precise fit. All this makes the Thraxis a tool that can always be relied on.

Outer boot
Thought through to the last detail, the Endo™ 2.0 construction rises to the challenge and gives you a boot that scores with flexibility and durability.
Endo is a completely new way of thinking about construction. The basis is an endo-skeleton made of urethane, which replaces the various layers in normal construction. Compared to conventionally glued and sewn frames, the Endo structure can be flexed as often as desired and always returns to its original position and strength at the end - without sacrificing performance. This creates a permanently consistent flex and a boot that always behaves neutrally in all conditions.
For ultimate grip and durability, the Vibram® V5 Outsole with cushioning Harshmellow™. You can't get more grip with less weight. 

Liner
With high-density, thermoformable Intuition® Pro foam and internal and external J-Bars, the liner has a precise fit and performance that meets the demands of a pro.
A 3D-moulded EVA insole rounds off the liner with plenty of comfort. In addition, the Thraxis offers the heat-reflecting Intuition® SpaceHeater™ liner. This liner makes your own body heat its ally and reflects it directly back to you. Warm feet, all season long. S'Cafe Coffee Mesh is made from 95 % recycled content and reduces odour build-up inside the boot.

Lacing system
With the patented BOA® Conda™ it is possible to open or re-lace the liner at any time without having to open the outer lacing. If you've tried it for the first time, you'll wonder how you managed without it.
The CONDA™ system is connected to the outer boot by a BOA® cog and wraps around the liner to keep your foot firmly in place. The focus is clearly on heel support and ankle support. You can choose how tight you want your liner laced and can conveniently adjust it individually. You can lace up the outer boot of the Thraxis quickly and easily with the H4 BOA® Coiler Lacing.
