Lange RS 90 SC Ski Boot 2025

All-in performance for lighter weight skiers. The Lange RS 90 SC LV Ski Boots feature a shorter cuff and flex suited to smaller skiers. They maximize speed and power transfer with race-proven tech and an innovative wind tunnel tested aero design. From the targeted power of Dual Core construction to its anatomical foot-hugging design, the RS responds to your every move as a natural extension of the body to maximize the efficiency and explosive power of every turn. It's built for expert skiers, instructors and racers looking for speed, power and precision on snow. A 90 flex suits lighter skiers seeking a performance boot with a softer flex.

Enhanced Power, Rebound and Control
Dual Core technology blends hard and soft plastics for targeted power transmission and boot flex, resulting in increased power, response and control

More Streamlined and Aerodynamic Than Ever
The RS race boot is more aerodynamic than ever thanks to our partnership with the Formula 1 Sauber-Alfa Romeo Racing team. Together, we developed the most aerodynamic ski boot on the market. The 'Air Flow' concept was born in their laboratory and shapes the future of sport. It's a revolutionary technology that optimizes the shape of the 3D-molded shell and introduces new buckles to reduce the coefficient of friction and air drag.

Amplified Power
Our Suspension Blade design connects the upper boot with the lower boot for smooth power absorption and transfer through the boot, putting more energy into your skiing

Adjustable Flex
Adjustable elastomers at the boot's two pivot points let you fine tune the flex to match your skiing. Choose from four elastomers of different stiffness ratings to dial in the flex

Out-of-the-Box Comfort, Precise Control
Customizable Dual 3D liners are preformed around the foot and ankle for out-of-the-box comfort that lets you explore more

Lightweight and Durable
Aluminum buckles offer reduced weight and increased strength for efficient closure and long-term durability

Precise, Low Volume Fit
Our Low Volume 97mm last is designed for low volume feet or skiers seeking a precision fit without sacrificing comfort
