For movement comfort on the climb and top performance on the descent, we pull on K2's Mindbender 105 BOA Ski Boot. The FastFit Instep features softer TPU that makes tugging this pair on easier, while the forefoot's BOA Fit System helps us dial in a perfectly snug fit. Built with a heat-moldable shell, cuff, and liner, the Mindbender 105 conforms to our feet for zero slop, ensuring the stiff flex picks up on our every move for optimal control at high speeds. When going for round two, the flip of the walk-mode lever and the easy hinging cuff pivot have us climbing comfortably thanks to the 50-degrees of unrestricted motion.
