The Lange RS 70 SC is the ideal ski boot for particularly lightweight or junior skiers looking for a sporty introduction to the world of performance ski boots.

All-around performance for lighter skiers. The RS 70 SC features a shorter cuff and a flex tuned for smaller or lighter-weight skiers. Speed and power transmission are maximized through race-proven technology and wind tunnel-tested aerodynamic design.

In the RS, Lange combines the targeted power of Dual Core construction with an anatomical, foot-hugging design. The boot responds to every movement as a natural extension of the body, maximizing efficiency and explosive power in every turn. This model is ideal for experienced skiers, ski instructors, and racers seeking speed, power, and precision on snow. A 70 flex is perfect for very lightweight skiers who want a high-performance boot with a softer flex.

Highlights

Enhanced power, rebound, and control
Dual Core technology combines hard and soft plastics for precise power transmission and a responsive flex, resulting in more energy, agility, 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, born in their lab, shapes the future of the sport, optimizing the 3D-molded shell and introducing new low-drag buckles to reduce friction and air resistance.

Race Flex Control
The brand-new Air Flow technology is complemented by another flagship innovation: Race Flex Adjust, a plate on the back of the boot that improves energy transfer between the shell and the cuff. The plate replaces the two traditional screws familiar to all racers and allows for softening the flex without introducing play or losing energy.

Optimal comfort, precise control
Customizable Dual 3D liners are pre-shaped around the foot and ankle to deliver optimal comfort—so you can explore more.

Lightweight and durable
Aluminum buckles reduce weight while increasing strength, offering efficient closure and long-term durability.

Precise low-volume fit
The 97 mm last is designed for low-volume feet and skiers seeking a precise fit without sacrificing comfort.

Technology

Aero Design
The “Air Flow” concept, developed in the lab, pushes the boundaries of ski boot engineering and defines the future of the sport. This revolutionary technology optimizes the shape of the 3D-molded shell and new buckles.

Race Flex Adjust
A plate on the back of the boot improves energy transfer between the shell and cuff. The plate replaces the two traditional screws familiar to racers, and the softer insert option allows for reducing the flex without play or energy loss.
