The Cochise 130 is Tecnica's powerful alpine and touring hybrid ski boot. The Cochise's 130 flex is the stiffest option available for experts and heavier skiers. The 130 flex offers the torsional response needed for everything from inbounds high speed cruising, to moguls and side and bc touring as long as weight isn't a priority. The boot includes tech fittings and a walk mode to use for touring bindings and a grip walk soles which can be used in alpine bindings. The boot has a remarkably comfortable fit out of the box, has a 99 mm last that is best for someone that is not low volume. It comes with Tecnica's heat-moldable C.A.S. liner that can be customized to your foot. An excellent all in one ski boot. THESE BOOTS WERE ONLY SKIED IN FIVE DAYS AND WERE NOT SUITED FOR MY LOW VOLUME FOOT.
