Power and Precision. The new RS 70 SC is the result of our deep understanding foot mechanics, fit, and ski boot behavior. Our new, race-developed Dual Core technology supplies incredible rebound and flex control for total control through the turn. The fit of the boot is medium with a 97mm last and with a 70 flex, it's aimed at a beginner. The short cuff is aimed at junior skiers and women as it accommodates for a smaller anatomy. The cuff measures 15mm in the back and 20mm at the front.  The anatomic shell design perfectly integrates with our new thermo-formable Dual 3D liner to deliver unparalleled comfort, precision, and power transmission. Be One with your boots, Be One with your goal. Product Code: FWSBG4BL0015 Lange RS 70 Short Cuff Ski Boot | Ski Boot
