Redeveloped and re-tweaked after ten years of freeride dominance the XV Snowboard Boot maintains the same blueprint of Xavier's signature Spark XV but with new revolutionary design features. This backcountry-bound boot offers exceptional support lively boardfeel and precise control for hiking skinning and riding. And although it's designed to handle the most extreme conditions in the backcountry it excels in any terrain with a stiff flex dual BOA lacing system and Hiker Flex construction that allows maximum mobility in forward and backward movement without compromising stable support. Plus we especially love the Stay On Track System which is a lateral and a medial reinforcement element to provide improved leverage when we need to navigate difficult traverses with confidence.
