The RXs are modern classics, a boot-fitter's favourite and on the feet of many happy skiers. Lange lose the fancy gimmicks and focus on excellence. The superior quality Dual Core construction simultaneously injects 2 densities of plastic at various points of the shell, meaning the balance between fit, comfort and performance could hardly be better. The dual pre-shaped and custom fitted liner provides great heel hold and grips the foot nicely whilst still allowing toe space. The choice of those in the know.
