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.

Product Details


Last: 100 mm – An average width last for those with average volume feet.

Dual 3D Pro Liner with Shin Control and Thinsulate™ – 100% customizable thermo liner with two types of high density foam and a precise, medium tension fit.

Shell Materials & Design

Dual Core Technology – A new "Power Injection" method allows Lange to inject two different durometers of plastic simultaneously through 5 injection ports, with the two plastics being directed to specific parts of the boot. The harder plastic goes to the heel, spine and lower shell to retain stiffness, while the softer plastic goes to areas that wrap the foot and lower leg for comfort.

Cuff – Polyurethane


Natural Stance – Lange's unique Natural Stance compliments modern ski designs, offering a lower ramp angle (4⁰) and more neutral, upright stance to increase balance and control for more efficient power transfer and less quad fatigue.
