Speed. Power. Precision. When every fraction of a second matters, the Lange World Cup RS ZA+ ski boots deliver podium-ready performance for top-level athletes. From explosive energy transfer to an uncompromising fit, and an aerodynamic design tested in a wind tunnel, every detail of these boots prioritizes precision and efficiency. The targeted power of the Dual Core construction responds to every movement as if it were a natural extension of the body, maximizing efficiency and power on every turn. A 130 flex offers high-performance power transfer for lighter-weight skiers.
Improved power, rebound and control Dual Core technology combines hard and soft plastics for targeted power transmission and flex, resulting in increased power, responsiveness and control More streamlined and aerodynamic than ever
The RS racing boot is more aerodynamic than ever thanks to our collaboration with the Sauber-Alfa Romeo Formula 1 team. Together, we developed the most aerodynamic ski boot on the market. The 'Air Flow' concept was born in their laboratory and is shaping the future of the sport. This revolutionary technology optimizes the shape of the 3D shell and features new buckles to reduce the coefficient of friction and air resistance.
Lightweight and durable Aluminum buckles offer reduced weight and increased strength for efficient closure that lasts Lightweight World Cup control The World Cup liner provides maximum support, rebound and transmission with a customizable, precision fit Race-ready performance fit Our 92+ mm last is designed for low-volume feet and skiers seeking a high-performance fit
