Thermo-formable materials are heated so that boot volume can be changed. The boot adapts itself to the foot.

Stability & Control
A wide Rottefella Nordic BC sole delivers the stability and control for wider skis and varied snow conditions

Extra Warmth
3M Thinsulate™ heat-retaining insulation delivers increased warmth in damp and cold conditions for all-day comfort and warmth

NBC Sole
Designed for backcountry Nordic boots, the NBC SOLE is manufactured by Rottefella with a wider sole and rotation axle, delivering superior stability for every snow condition.

Dual Core
As you drive and flex into your boots, DUAL CORE actively compresses and expands -- harnessing potential energy to deliver explosive power, snap and rebound. Imagine World Cup precision and response, easy entry-and-exit, and a new level of ski boot performance as reactive and dynamic as your own body.
