For decades, skiers with wide and high volume feet who wanted to tour were left "wandering in the wilderness," so to speak, but that changed with the introduction of the Tecnica Cochise HV 120 DYN Alpine Touring Ski Boots. Already a classic in the land of the Sasquatch, the Cochise HV gives you all the great features of the regular Cochise with more room across the metatarsals and over the instep. Product Details Fit Last: 102mm – A wider last designed for high volume feet C.A.S. Shell – The C.A.S. shell has an anatomical shape that matches the foot shape. This allows for a better out-of-the-box fit. Dimples on the shell reduce surface tension and facilitate the thermo customization process, making it easier for a bootfitter to modify the shell to fit your foot. Flex Flex: 120 – A stiff flex for expert skiers who require quick rebound and ski response. Liner Performance C.A.S.
