Designed specifically for advanced, expert or professional female skiers looking for a traditional 4 buckle, all mountain boot, the Mach1 105W is perfect for someone that doesn’t want to compromise performance but is looking for a slightly relaxed women's specific fit. Designed off the last and stance of the world cup boots for high performance, the Mach1 relaxes the fit to a 100mm for those needing a medium volume fit and Quick Instep makes getting them on and off a breeze. The more anatomical and lower scalloped cuff combines with a perfectly sculpted lower shell featuring an incredibly well defined, narrower heel pocket, a pre-punched navicular area over a sveltely contoured medial wall, which flows elegantly into an asymmetrical, elongated toe box for all day comfort and warmth. The C.A.S. liner gives unmatched out-of-the-box fit, and the unique outer material allows for numerous customization options. It pairs perfectly with the shell to give the skier unrivaled snow feel and precision. A solid 105 flex will give experts to advanced women alike plenty of power and input for any terrain encounter. The interchangeable soles with TecniGrip for traction are easily replaced, or you can put on a solid, pre-canted sole (sold separately) for any alignment issues you may have. The unrivaled fit combined with legendary Tecnica performance makes this boot an all day performer that should be on your short list for 2014.
