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 K2's collection, this snowboard boot services even the most demanding of riders. 

Lacing System: BOA
Response: Responsive

Features:

• 3-Point Harness Liner Lacing - A traditional liner harness with a pull lace and three contact points hugs the ankle and provides additional support.
• Rubber Reinforced Articulating Upper Cuff with Endo™ 2.0 - Reinforced materials in high wear and flex zones extend the boot's life and deliver a distortion-free flex. At the same time, Endo™ 2.0 helps to retain boot flex and durability over the lifetime of the boot.
• Flex Zone Upper with Rubber Lower - Minimal seams, minimal parts, and durable as hell. A snowboarding-first, the all new one-piece rubber lower found in the Orton was designed and developed to meet the demands of Sage Kotsenburg
