The new Mach 1 120 HV from Tecnica is an excellent ski boot for strong skiers or bigger guys who have a medium to wide forefoot and medium to wide calf volume. Tecnica's Quick Instep Technology has a softer injection of plastic across the top of the foot that allows your foot to slide into and out of the shell effortlessly. The Lift Lock Buckles are highly durable, adjustable and are able to stay buckled all day when you are getting after it on the mountain. The C.A.S. (Custom Adaptive Shape) Shell is easily customizable for a bootfitter to shape the shell. Dimples hold a punch much easier and more accurately than any other shell ever constructed. The C.A.S. Celliant Liner has customization in the heel and ankle pocket that can be heated, molded, shaped and grinded for a performance oriented fit, with a strong heel hold and energy transmission. A 45mm Power Strap keeps a secure fit across your shin, while adding rebound to each turn. If you are a strong skier looking for an accommodating fit with enough power for aggressive skiing, the new Mach 1 120 from Tecnica is a great choice.
