Speed. Power. Precision.
When every fraction of a second counts, the Lange World Cup RS ZA+ Ski Boots deliver podium-proven performance for elite-level athletes. Engineered for explosive energy transfer and an uncompromising fit, every detail is crafted for maximum efficiency and control — down to the wind tunnel-tested, aerodynamic shell.
Key Features:
🔹 Explosive Power Transfer with Dual Core Technology
Dual Core construction fuses hard and soft plastics for a dynamic flex pattern that responds instantly to every input. The result? Unmatched rebound, power transmission, and control through every turn.
🔹 Race-Bred Aerodynamics
Developed in collaboration with the Sauber-Alfa Romeo Formula 1 team, the RS boot features our revolutionary Air Flow design. The reshaped 3D-molded shell and redesigned buckles reduce air drag and friction — making it the most aerodynamic ski boot ever created.
🔹 High-Performance Flex
A race-calibrated 130 flex delivers elite-level energy transmission for lighter weight skiers demanding maximum precision and control.
🔹 World Cup Fit and Feel
Engineered with a 92+mm last, the RS ZA+ offers a low-volume, race-tight fit for maximum responsiveness. The World Cup liner provides exceptional support and rebound, with customizable comfort for elite-level performance.
🔹 Lightweight Durability
Reinforced aluminum buckles reduce weight while enhancing closure strength — built for the demands of race-day intensity and long-term use.
