The Lange RX 120 GW Ski Boots are a stone cold classic for expert all-mountain skiers the world over, combining the power and precision needed to drive your skis to their maximum potential with the comfort and smooth, progressive flex that make them feel like part of a well-oiled machine (you, your boots, and your skis). The Dual Core polyurethane construction mimics the Lange World Cup design that's been on the top of so many podiums, but in a softer formula, while the Dual 3D Pro liner offers fantastic heel retention and the warmth of Thinsulate™ insulation (the stuff that goes in your gloves). New for this season is Gripwalk soles on all of the RX models, for easier walking or booting to that new line.
