Dual Core blends two different densities of plastic in the shell. Harder plastic in power zones (shin, instep) for maximum energy transfer. Softer plastic in comfort zones (ankle, calf) for better wrap and reduced pressure. The result is a boot that drives like a race boot but fits more comfortably than a single-material construction.

How does the RS 110 MV compare to the RS 120 MV?

Same Dual Core shell, same 100mm last, same Race Flex Adjust. The 120 MV is stiffer (120 vs 110 flex) and $100 more ($800 vs $700). Choose 110 for a more forgiving flex; 120 for maximum stiffness and response.

Description

All-in performance. The Lange RS 110 MV Ski Boots maximize speed and precision with race-proven technology and an innovative, wind-tunnel-tested aerodynamic design. From the targeted power of Dual Core construction to its anatomical, foot-hugging fit, the RS is designed to be a natural extension of your body, unlocking efficiency and explosive energy in every turn.

Expert skiers, instructors, and racers will appreciate the 110 flex, which balances power and responsiveness with a slightly more forgiving feel, ideal for lighter skiers or those seeking longer, all-day comfort without sacrificing precision.

Enhanced Power, Rebound, and Control
Dual Core technology blends hard and soft plastics for targeted energy transmission, rebound, and flex, ensuring responsive handling at speed.
Streamlined Aerodynamics
Developed in partnership with the Formula 1 Sauber-Alfa Romeo Racing Team, the RS introduces the revolutionary Air Flow shell design and re-engineered buckles to reduce drag and maximize downhill speed.
Race Flex Control
Featuring the new Race Flex Adjust plate at the back of the boot, skiers can fine-tune flex without energy loss. Unlike traditional screws, this system boosts stability and efficiency for aggressive skiing.
Custom Fit Comfort
Dual 3D pre-shaped liners contour around the ankle and foot for an out-of-the-box fit with high-performance precision.
Durable, Lightweight Hardware
Strong, lightweight aluminum buckles deliver secure closure and long-term reliability.
Medium Volume Fit (100 mm Last)
Balanced width ideal for medium-volume feet or skiers seeking slightly more room for all-day comfort.

The RS 110 MV is the entry point into Lange's race-derived RS line for medium-volume feet. Dual Core construction blends hard and soft plastics in the shell for targeted power transmission — hard where you need support and energy transfer, soft where you need wrap and comfort. The Race Flex Adjust plate at the back replaces traditional screws and enhances energy transmission between shell and cuff. The mono-material GripWalk-compatible sole provides binding flexibility.

At $700, this is premium race-performance territory. The 100mm Performance Fit last provides more room than Lange's traditional LV (97mm) race boots, making it accessible to expert skiers and club racers with medium-width feet. Flex 110 is the more forgiving option in the RS line — still stiff enough for aggressive carving but manageable on longer days compared to the RS 120 MV.

Strengths

+Dual Core construction — race-level power transfer with some comfort zones
+Race Flex Adjust for enhanced shell-to-cuff energy transmission
+100mm Performance Fit — race boot precision accessible to medium-volume feet

Best For

Expert and club-racing skiers with medium-volume feet who want Lange's race-derived performance at a more manageable flex.

Limitations

−Premium $700 price for race-oriented construction
−No walk mode — dedicated piste/race boot (GripWalk-compatible sole requires compatible bindings)
−Race-oriented ergonomics may feel aggressive for all-mountain cruising

Not For

Wide feet (100mm is the widest RS option), all-mountain skiers who need walk mode, intermediates, or anyone who needs a softer flex.
