The Tecnica Cochise 130 DYN is designed for backcountry skiers with average sized feet. CAS technology works to make the boot lightweight but also customizable for the perfect fit. The Power Light Design makes the frame thinner and 2.5x stiffer than conventional boot material. Hike/ski mode on the back spine and GripWalk soles make walking easy and more comfortable. With a 99mm last and stiff 130 flex, this boot offers a tight fit for peak performance off-piste.
