All-in performance for lighter weight skiers. The Lange RS 70 Short Cuff Low Volume Ski Boots are engineered with a shorter cuff and flex specifically tailored for smaller skiers. These boots maximize speed and power transfer with race-proven technology and an innovative, wind-tunnel-tested aero design. Dual Core construction delivers targeted power and control, while the aerodynamic 'Air Flow' concept reduces drag. A 70 flex suits the lightest skiers seeking a performance boot with a softer flex. The low volume 97mm last ensures a precision fit, and customizable Dual 3D liners provide out-of-the-box comfort.
