LANGE WORLD CUP RS ZSOFT+

In collaboration with the Formula 1 team Sauber-Alfa Romeo Racing, we conducted wind tunnel tests to develop the most aerodynamic ski boot on the market.
The "Air Flow" concept originated in their laboratory, pushing the boundaries of science and shaping the future of sport.
This revolutionary technology optimizes the 3D shell shape and features new buckles.
Our brand-new Air Flow technology is complemented by another cutting-edge innovation: the adjustable race flex, a plate on the back of the boot that improves energy transmission between the shell and the cuff. The plate replaces the two conventional screws familiar to all racers. The even softer insert offers the ability to soften the flex without creating play or loss of energy. Our new RS boot is the result of a complex assembly of parts, seamlessly integrated for maximum performance and efficiency
