You will experience the ease of putting on your Alltrack 70 without any hassle, with incredible ease, thanks to STEP IN technology. A simple upward pull of the lever at the back opens the boot widely, allowing your foot to slide in effortlessly. You close the buckles and you're ready to ski. A 102 mm last provides an excellent balance between fit and comfort. The soft liner, made with sheep wool, is thermoformable and insulated with Thinsulate™ for added warmth.
