Light, agile and supportive, this is the boot for climbers who ski their descents. The patented 360° rotating cuff delivers unrivaled vertical and lateral ankle agility while climbing. On ski descents, it locks in place and employs a carbon-fibre reinforced construction for support and power transfer to the ski. A zippered gaiter provides protection, and the closed-cell liner is warm and moldable for a custom fit. A redesigned power strap and upgraded pivot-point washers improve durability.
