Step into World Cup-level performance with the Rossignol X11 Ski Boot, engineered to deliver the podium-worthy control that intermediate and expert classic cross-country skiers demand. Built with proven X-ium series technology and a recycled fiberglass-injected heel counter, these boots transform every stride into powerful, stable energy transfer through your skis, whether you're training for competition or pushing your limits on groomed tracks. The innovative over boot design with central zipper seals out snow while providing essential insulation against wind and moisture, keeping your feet warm and dry during those long winter sessions. Quick speed lacing means you'll spend less time in the lodge and more time carving up the trails, making these boots the perfect choice for serious skiers who refuse to compromise on performance or comfort.
