TECNICA COCHISE 100 Tecnica Cochise 100 24/24.5cm Backcountry Ski Boots Last: 100 Flex: 100 Sole Length: 290mm 3-buckle system. Lightweight boots specifically designed for backcountry skiing. Equipped with a hike mode, making them comfortable for travel from the parking lot to the slopes and around the ski resort. Although they are backcountry boots, I used them without any problems with regular on-piste ski bindings. I used these for a total of about 10 days for backcountry and on-piste skiing. As they have been used, there are scratches as shown in the photos, so please purchase only if you understand this. They will be shipped in the original box.
