Medium flex and a responsive feel with a Dual-Zone BOA® Fit System for precise fit control With a legacy of pushing personal skills to the pro level, the men's Burton Ruler Snowboard Boots are the choice for stepping to larger drops, hitting burlier features, and pushing your skills. The ability to independently dial in the tension between the upper and forefoot lets you fine tune the fit and feel to match your ambitions. Their proven formula creates a medium stiff, responsive feel that's equally nimble and powerful. Warm feet and a custom fit keep you riding longer and thinking about your feet less. Features: A not too stiff, not too soft flex means you can push your skills without being pushed around. A Dual-Zone BOA® Fit System lets you independently micro-adjust the fit and feel of the forefoot and upper to exactly how you want it. Lightweight, heat-moldable liners offer a custom fit with the tech to reflect heat and wick sweat to keep your feet warm and dry all day, all season.
