The K2 Thraxis is K2’s stiffest and most performance-driven boot, engineered for advanced to expert riders who demand precision, control, and durability. With a stiff 10/10 flex, it excels in high-speed all-mountain and freeride scenarios. The Thraxis combines a triple BOA® lacing system with a heat-mouldable liner for ultimate heel hold and comfort, while the Vibram® outsole with HarshMellow™ cushioning absorbs chatter and ensures traction in all conditions.
Aggressive riders will appreciate its precise power transfer, supportive cuff, and customizable fit, making it ideal for carving, big mountain lines, and technical terrain.
