Speed. Power. Precision. When every fraction of a second counts, Lange World Cup RS ZA ski boots deliver maximum performance to elite athletes. An iconic, race-proven model, the new-generation RS has been refined to help you go even faster. A smooth, aerodynamic design tested in the wind tunnel, efficient energy transfer and an uncompromising fit: every detail of these boots puts precision and performance first. Built with Dual Core construction, the World Cup RS ZA responds to your every move like a natural extension of your body, for perfect control in every turn. With a stiff 130 flex and a 92 mm last, it delivers responsiveness and an ultra-precise fit for the most demanding skiers. From the start gate to the finish line, become one with your boots.
Improved power, rebound and control
Dual Core technology combines materials of different stiffness to give the skier greater responsiveness, more power and explosive rebound for increased performance.
A smoother, more aerodynamic design
The new RS race boots are more aerodynamic than ever thanks to a collaboration with the Sauber Alfa Romeo Racing Formula 1 team. Together, they developed the most aerodynamic ski boot on the market. The "Air Flow" concept was born in the team's wind tunnel to help you go even faster: a revolutionary technology that optimises the shape of the shell to improve air penetration and reduce drag.
World Cup-level control and precision
The new World Cup liner comes straight from racing. Designed with minimal seams and heat-mouldable inserts for greater customisation, it offers maximum support, a precise fit and absolute control.
Lightweight and durable
Aluminium buckles reduce weight and increase strength for efficient closure and long-term durability.
Ultra-precise, race-ready fit
The ultra-precise 92 mm last is designed for narrow feet and for skiers looking for the most precise fit possible.
