The Lange World Cup RS ZA+ is a no-compromise race boot built for elite athletes who demand maximum speed, explosive power, and absolute precision. Delivering podium-proven performance and featuring a wind tunnel-tested aerodynamic design, every detail is engineered for top-level efficiency and control.

The innovative Dual Core construction acts as a natural extension of your body, maximizing power transmission in every turn. By combining different plastic densities, it delivers the perfect balance of precision, responsiveness, and control – built for uncompromising race performance.

Developed in collaboration with the Formula 1 Sauber-Alfa Romeo Racing Team, the boot stands out with advanced aerodynamics. The Air Flow technology optimizes the 3D-shaped shell and reduces drag and friction through innovative buckle design – a crucial advantage in competition.

Lightweight aluminum buckles ensure strength, reduced weight, and long-lasting durability, while the World Cup liner provides maximum support and a precise, customizable fit. With a 92+ mm last, the RS ZA+ is specifically designed for narrow feet, delivering a race-focused, high-performance fit.

Thanks to the Race Flex Adjust technology, the flex can be fine-tuned to optimize energy transfer and minimize energy loss.
