The Lange RX 130 LV Ski Boot is the narrow version of the stiffest all-mountain alpine boot offered by Lange. It's built on a race chassis for exceptional control and performance. Like a race boot, it features four aluminum buckles for the foot hold and heel lock you expect from Lange, with an aggressive 97mm last for riders with narrow feet. This beast of a boot will make sure you can rip big-mountain lines, crush powder fields, and lay trenches on groomers. To achieve this level of performance the RX 130 is equipped with a two-piece, dual-core plastic shell, heat moldable Dual 3D full liner, and a neutral upright stance. The dual-core shell helps lock your foot in and effectively translates power to the edge of your skis for a responsive ride and quick maneuvering. To make sure your foot is comfortable inside that hard plastic shell, the Dual 3D full liner can be heat molded for a custom fit that will prevent your foot from sliding and keep the blood flowing so you can actually feel everything you're doing. Combining the moldable liner with a more neutral and upright stance provides more comfort and rideability, letting you rip from bell to bell without stopping to give your feet a rest.
