The Rossignol Men's Alias 90 Ski Boots make a perfect ski boot for the bigger, stronger intermediate skier who has a medium to wide foot and leg shape. They deliver a comfortable, generous fit without sacrificing powerful, all mountain performance. Featuring a 104mm "wide" fit, the Alias retains a contoured forefoot, strong heel cup and asymmetrical toe box for incredible comfort and support right out of the box. Sensor Fit technology addresses all of the common problem fit areas, providing an accommodating instep and more articulate ankle area for increased comfort, circulation and warmth.
