From explosive energy transfer to uncompromising fit, every detail of these boots prioritizes precision and efficiency right down to the wind tunnel engineered aero design. The targeted power of Dual Core construction responds to every move as a natural extension of the body for maximum efficiency and power through every turn. A 110 flex offers high-performance power transfer for the lightest weight skiers.

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.

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

World Cup Control
World Cup liner offers maximum support, rebound and transmission in a customizable, precision fit
