An icon in the ski industry, the Lange RX 130 Ski Boots remain a huge favorite of bootfitters and industry pros who continue to appreciate its smooth progressive flex and superb snow feel. The switch to Lange s new Dual Core molding process only made the flex smoother, and the Dual 3D Full liner locks your heel in place like no other. If combining comfort with performance just a notch down from a full race boot sounds like a good idea to you, the RX 130 is your boot.
