Are you the type to crank your boots to eleven at every possible opportunity? Are all of the boots you’ve tried simply too soft? Meet the Mach1 MV Concept Boot, boasting a 140 flex for ultimate stiffness, power transmission, and an ability to hold an edge going irresponsibly fast. With a race inspired design, the Mach1 Concept pushes the limit of what's possible on skis, and thanks to a customizable tongue liner and micro-adjustable aluminum buckles you can wield the power of this boot in a comfortable, customized fit. The asymmetrical shell offers incredible power transmission and encourages the skier to push all of the energy from the exit of the turn directly into the ski on the following turn. As the most aggressive boot in Tecnic’s line, the Mach1 Concept is ready for whatever you can throw at it.
