The stiffest, most aggressive all-mountain/freeride offering from Lange the RX 130 packs a mean punch. With a 100 mm forefoot and a narrow heel pocket, this boot is designed to securely hold a wide variety of foot shapes. The 130 flex is smooth and stiff due to the mono-injected shell and cuff. Lange s Control Fit liner has anatomical padding for increased performance and warmth, and the replaceable Ultra Grip soles keep you locked in when hiking to your favorite stash. For boots that are as comfortable as they are hard-charging, check out the Lange RX 130 Ski Boots.
