Advice : Use the foot sizer from SIDAS to help you find the right size
The RS 120 MV is a men's ski boot from the Lange brand designed for expert skiers, racers, and instructors seeking speed and precision.
The Dual Core construction, developed by the brand’s racing department, is made with high-quality materials and delivers optimal stiffness. Flexible in comfort yet uncompromising on performance, these boots provide power, liveliness, and precision. This technology also offers better flex control. Finally, the Race Flex Adjust plate ensures improved energy transmission between the shell and cuff, while the Air Flow technology optimises the boot’s shape to go ever faster.
On the comfort side, there is the Dual 3D Full liner. Fully customisable with three high-density foams positioned on key zones, it offers a tailored fit and maximum comfort and support. Furthermore, its 100 mm fit was specially developed for skiers seeking less compression on the foot, favouring comfort without compromising performance.
Designed in collaboration with the Sauber-Alfa Romeo Racing Formula 1 team, the RS 120 MV is a model created for competitors and instructors who want to perform on the slopes and reach their goals.

| DUAL CORE | The Dual Core technology combines materials of different stiffnesses to offer the skier greater responsiveness, more power, and explosive rebound for enhanced performance. |
| AIR FLOW | This revolutionary technology optimises the shell shape to increase the air penetration coefficient, thereby improving drag reduction. |
| RACE FLEX ADJUST | Available in two densities, this plate located at the back of the boot ensures better energy transfer between the shell and cuff. In its softer PU 53 version, it allows the flex to be softened by 8% without creating play or energy loss. |
| DUAL 3D FULL LINER | The anatomical and pre-shaped DUAL 3D FULL liners perfectly conform to the shape of the foot for a more comfortable fit, precision, and optimal foot hold. They are fully customisable with three high-density foams placed in key areas for a tailored fit and maximum comfort and support. |
| FIT PERFORMANCE | Lange's FIT PERFORMANCE offers a precise but more comfortable 100 mm last. It is designed for medium-width feet and those seeking a softer foot compression for greater comfort. |
