For swift and light ascents and big mountain lines: if you are looking for the ultimate fusion of weight savings and performance, look no further than the Fischer Ranger Free 130 Alpine Touring Ski Boot. Designed for use by the most aggressive skiers who are looking for a no compromise fusion of a touring boot and a downhill boot. The shell and cuff are made of Grilamid, an ultralight composite similar to Kevlar, and the latter is reenforced with carbon fiber for extra stiffness when you really lean into the boot. Top buckle walk mode switch makes it easy to flip from up to down and the Vibram GripWalk rockered soles will give you traction on the slipperiest of ridgelines.
