The Tecnica Mach Sport HV 80 is a great ski boot for the solid intermediate skier who has a medium to wide forefoot and medium to wide leg shape. Tecnica's C.A.S. (Custom Adaptive Shape) Shell uses dimples that make it very easy to shape the shell if you need it. The dimples hold a punch much better than other shells as well as providing the bootfitter an easy map to the area that needs more space. The upper cuff buckle has a Ratcheted Closure that allows you to easily dial in the perfect fit across your leg. The new Lift Lock Buckles are very durable, and stay open when you want them open so they don't close shut on you when you are taking your boots off. The PE Light Celliant Liner uses minerals that transfer your body heat into infrared energy to keep your feet warm on those cold January days. A Double Quick Instep uses a softer injected plastic across the top of the foot that helps your foot slip in and out of the shell with ease. If you are a budding intermediate looking for comfort and support, the Mach Sport HV 80 is a great boot for you. Best Fits a Medium to Wide Forefoot and Medium to Wide Leg Shape, C.A.S.
