The Rossignol X3 Touring Boot is the go anywhere, do anything boot for the skier who might start the day on the classic track and end deep in the backcountry. The X3 Touring Boot fits an NNN binding. It's burly enough to blaze trails through the woods or over a frozen lake, but it's also light enough to use on the track when you don't feel like putting in the extra work to break trail. The PVC lace cover means you don't have to thaw your boots in your car before untying them at the end of a long tour. Rossignol built the X3 Boot with a nylon midsole which offers a compromise between power and comfort. The boots are stiff enough to control the skis while you're turning, and soft flexing enough to be comfortable.
