The Rossignol X11 Skate Ski Boot brings World Cup-inspired performance to intermediate and expert skate skiers who demand competition-level responsiveness on the trails. Built with a recycled fiberglass-injected cuff and carbon midsole insert, these boots deliver the stiff, precise power transfer that separates good skiers from great ones, while the thermoadjustable liners heat-mold around your feet for a truly customized fit that eliminates pressure points during those long training sessions. The WINTHERM® breathable membrane keeps your feet warm and dry without the sweat buildup that can ruin a perfect day on the snow, while the central zipper overboot seals out snow so you can focus on perfecting your technique rather than dealing with soggy socks. Whether you're chasing personal bests or podium finishes, the X11's asymmetric support system and skate-optimized flex pattern give you the confidence to push harder and ski faster than you thought possible.
