The Mach 1 MV 75 from Tecnica makes a great boot for the solid intermediate skier with a medium to narrow forefoot and leg shape. Tecnica has added a CAS (Custom Adaptive Shape) Cuff Adapter this season to give you the ability to fine tune the fit across your leg. The UltraFit W Liner has a pre-shaped women's specific fit with more taper moving from the mid-foot to the heel to prevent any slipping and extra comfort. The Mach 1 75 has the CAS Shell that has strategically placed dimples in the most common areas for a bootfitter to customize. Those dimples hold the shape of a punch and take less effort to move the shell. If you want stability and comfort in one tight little package, the Tecnica Mach 1 75 is the boot for you.
