The Tecnica Cochise 120 DYN is a ripping boot for aggressive skiers who have a medium to narrow forefoot and medium to narrow leg shape. Tecnica's Mobility Cuff offers a 42 degree range of motion in hike mode for easy and efficient skinning or hiking for some deep turns. The C.A.S. (Custom Adaptive Shape) UltraFit Pro Liner has customizable material in the heel and ankle pocket that delivers a precise heel lock and a high amount of power transmission. The C.A.S. Shell uses dimples to provide a bootfitter with an accurate map on areas to punch. These dimples hold a punch much better, while requiring less pressure to shape the shell. Lift Lock Buckles stay open when you want them to and stay clamped when you need them to. A 45mm Power Strap keeps a snug wrap across your shin, while delivering a strong amount of rebound. If you are a powerful skier looking for a responsive boot that is easy to customize, the Tecnica Cochise 120 DYN is an excellent option for you.
