Lange is upping their XT Free game this season, adding a 120 flex for those who felt the 130 was a bit stiff but the 110 a bit soft, as well as bringing their proven Dual Core molding technology introduced last season in the RX models to the table. That's nothing but good news for all-mountain skiers like you, and the Lange XT Free 120 Alpine Touring Ski Boots promise to be just the ticket for those who want to do a mix of lift skiing and touring on one boot.
