The second-stiffest boot in Tecnica's Cochise freeride touring line, the Cochise 120 Men's Ski Boot's an ideal blend of uphill performance, downhill shredability, and comfort. It's built on a 100mm last, which offers slightly more room than the top-shelf Cochise 130, but rocks a 120 flex that's burlier than the 110 for more gnar-thrashing power on the descent. Other than that, it's the same, and that's more than all right. Tecnica made the shell out of new Triax 2. 0 plastic, which is nice and stiff but 10% lighter than the original Triax, making the uphill slog a little easier, and redesigned the lower shell for better heel hold and less toe crunch. The Cuff Mobility System ski/walk mode also offers eight degrees more rotation this time around, giving you a more natural stride to take the hip-flexor pain out of longer approaches. You'd expect a Tecnica to have bomber downhill performance, and, well, the 120 doesn't disappoint. It comes kitted out with a snug, sturdy UltraFit Pro liner that wraps your foot and resists packing out, and a PowerLock top buckle/power strap combo that provides a super-snug and sturdy wrap around your shin and calf for power and control. Three more rugged aluminum buckles lock the shell down around your foot, and the asymmetrical toe box provides a high-performance fit without cobra-squeezing your toes to death. Tecnica also equipped the Cochise with interchangeable sole technology, so you can swap in tech soles (sold seperately) for the included Techni-Grip rubber soles if you want to go for a full-on tech setup, and included a easy-flexing Quick Instep panel for easy on and off, even when temperatures are hovering around "North Pole in January" levels.
