The Cochise 120 Dyn from Tecnica is a ski boot that brings together a stiff flex and generous cuff movement in a mid-volume shell. It’s aimed at skiers who need solid support on the descent without giving up mobility when moving on foot.
With a flex rating of 120, this boot offers firm resistance for precise edge control and stability at speed, while its 42° range of motion lets you walk or skin with less effort and a more natural stride. The mid-volume fit balances a secure feel with enough room for comfort throughout a long day on the mountain.
In ski boots, the flex rating measures how much the cuff resists forward bending—a higher number means a stiffer boot that transfers power more directly to the ski. The 42° of cuff rotation refers to how far the upper shell can pivot, giving you extra freedom when you’re hiking or touring before you lock in for the ride down.
