The Lange RS 100 SC Wide is ideal for experienced skiers, ski instructors, and racers seeking speed, power, and precision on snow.

The RS 100 SC Wide features a shorter cuff and a flex tailored for lighter-weight skiers. Speed and power transmission are maximized through race-proven technology and a wind tunnel-tested aerodynamic design.

Within the RS boot, Lange combines the targeted power of Dual Core construction with an anatomical, foot-hugging shape. The boot responds to every movement as a natural extension of the body to maximize efficiency and explosive power in every turn. A 100 flex is ideal for lighter skiers who want a high-performance boot with a slightly softer flex. The Lange RS 100 SC Wide is your tool for carving powerful turns across the mountain.

Highlights

Enhanced power, rebound, and control
Dual Core technology fuses hard and soft plastics for precise energy transmission and dynamic flex, resulting in more power, responsiveness, and control.

Sleek and more aerodynamic than ever
Thanks to Lange’s partnership with the Sauber-Alfa Romeo Formula 1 Racing Team, the RS race boot is more aerodynamic than ever. Together, they’ve developed the most streamlined ski boot on the market. The “Air Flow” concept was born in their lab and is shaping the future of the sport. Revolutionary shell shaping and new buckle design reduce drag and friction coefficient for unmatched aerodynamics.

Race Flex Control
The new Air Flow technology is complemented by another flagship innovation: Race Flex Adjust. This rear-plate design improves energy transfer between the shell and cuff, replacing the traditional dual screw system familiar to racers. The softer insert allows fine-tuning of flex without introducing play or power loss.

Optimal comfort, precise control
The customizable Dual 3D liners are pre-shaped around the foot and ankle for optimal comfort and control—so you can ski harder, longer.

Lightweight and durable
Aluminum buckles reduce overall weight while increasing durability and offer secure closure and lasting performance.

Comfort fit for medium-volume feet
A 100 mm last is designed for skiers with medium-volume feet or those who prefer a slightly roomier fit for all-day comfort.

Technology

Aero Design
Developed in a lab setting, the "Air Flow" concept pushes the boundaries of design science and shapes the future of ski performance. This cutting-edge technology optimizes the shape of the 3D-molded shell and introduces new aerodynamic buckles for reduced drag and improved efficiency.

Race Flex Adjust
A plate located on the rear spine of the boot improves energy transmission between the cuff and shell. Replacing the traditional dual-screw setup, this innovation allows flex to be softened without compromising support or power transmission.
