The Cochise is Tecnica's bread & butter for backcountry touring, and this Cochise 130 Dyn is the stiffest option available for experts and heavier riders. A touch of carbon creates a powerful 130 flex that offers the torsional response needed for dropping powdery mountains, hucking off cliffs, and keeping upright in spring's icier conditions. We like this boot's remarkably comfortable fit that balances a precise 99mm last with Tecnica's thermo-moldable C. A. S. technology that can customize the boot's shape to our foot's contours after a quick stop at the local bootfitters.
