The Exclusive RX 90 combines Lange's Exclusive women's fit with Control Fit Technology for a high performance ski boot tailored to the needs of expert female skiers. New Control Fit technology and a mono-injected shell give this boot the best "out of the box fit" imaginable while allowing for easy customization when necessary. The faux-fur Control Fit Liner addresses traditional hard to fit issues using a true lasted liner, one piece toe box, instep pocket and saddle stitched seams alleviating common pressure points and increasing circulation. By combining a 100mm last with a slightly snugger ankle fit than its competitors the Exclusive RX 90 delivers a level of comfort, warmth and precision fit that no other women's boot in its class can match.
