K2 Thraxis 2026 Boots de snowboard

Maximum control in all conditions – the K2 Thraxis Boot

If you’re seeking uncompromising performance, the Thraxis is your boot. Designed for technical lines, long days on the mountain, and riders who demand precision, this boot features a triple BOA® Fit System, a heat-reflective Intuition® SpaceHeater™ liner, a reinforced Flex Zone upper, and a Vibram® V5 outsole with EcoHarshmellow™ cushioning. From custom fit to high-end dampening, you can count on the Thraxis.

Outer boot
The rubber-reinforced Flex Zone upper, made with HDR Premium Synthetics, offers long-lasting durability and natural movement. The Endo™ 2.0 construction features a resilient urethane backbone that returns to its original shape repeatedly, providing consistent flex and stability over time. Coupled with the lightweight Vibram® V5 outsole and enhanced EcoHarshmellow™ Pro cushioning, it ensures maximum grip and comfort with minimal weight.

Liner
The Intuition® Pro Foam 3D Liner featuring SpaceHeater™ technology retains your body heat, ensuring your feet stay warm all day. Internal and external J-Bars with contoured ankle pockets deliver a secure heel fit. The S’Cafe™ Coffee Mesh reduces odours and maintains freshness with fibres made from recycled coffee grounds.

Lacing system
Both outer and inner boot can be adjusted independently: The BOA® Fit System featuring H4 Coiler™ with TX3 laces provides zone-specific outer lacing. Inside, the BOA® Fit System featuring Conda™ keeps your foot securely in the liner. In addition, a third BOA® dial on the cuff offers targeted support for the shin – individually adjustable, easy to use with gloves, and quick to readjust at any time. The BOA® Fit System delivers micro-adjustable precision fit, engineered to perform in the toughest conditions.
