About Rossignol BC X9 Boots: Hey, I’m Robert Laziloni, the division mamger for Rossignol based in Park City, Utah. This is the BC X9 Boot using the Rotifilah NNN BC sole, which is much wider and stonger axes than the regular cross-country boot. That will give you a lot of stability when you go out of track. We have a free mobile upper cuff that give you very good support and when you turn down. Ratchet buckle, full cover lace, thermofit inside which can adjust to your feet. Again, very light boots and a lot of fun to control our BC ski with that.
