The Lange RX 130 is a high powered boot for experts that are looking for a boot that will drive a strong edge when you lay them down, and give you powerful rebound with every turn. Lange's Control Fit Liner has a one piece toe box, so you will never feel that pesky seam across the top of your toes, an instep pocket to keep your blood circulating, for added warmth, and a power wedge tongue to give you a snug wrap across your shins. The Natural Stance of the RX 130 is designed for the modern fat and rockered skis that your should be on by now, to give you better balance and power transfer. A Mono-Injected Polyether lower shell keeps a consistent flex at varying temperatures, and is very easy for skilled bootfitters to customize. To seal the deal on this bad boy a 40 mm Camlock Power Strap acts like a fifth buckle to give you more leverage as you power down the mountain. The RX shell best fits skiers with a medium to narrow forefoot, narrow leg shape, and is truly one of the best boots for taller, slender skiers. If you want a high powered boot that can be customized very easily the Lange RX 130 will be a great boot for you.
