When the map fades and the trail disappears, the BC X 6 carries you forward. Designed for narrow to mid-width backcountry touring skis, it balances the stride efficiency of a Nordic boot with the stability needed for steeper, ungroomed terrain. It’s built for skiers who measure distance in quiet miles and choose their own line through the trees.

A hinged external cuff provides lateral support and torsional rigidity without restricting natural fore/aft motion. The result is a boot that tours freely on the flats yet feels composed when the terrain tips downhill. The wide NNN BC sole—developed by Rottefella—creates a stable platform for variable snow, offering confident control when conditions shift from powder to crust.

Warmth is not an afterthought. A thermo-moldable liner with 3M Thinsulate™ insulation surrounds the foot in heat-retaining comfort, while a tall external gaiter and durable lace cover seal out snow and moisture. The fit can be customized through heat molding, ensuring precision without pressure points.

From breaking trail at first light to navigating the final descent home, the BC X 6 is a dependable partner—warm, supportive, and ready to explore beyond the track.
