They are size 178, center mounted, boot size was 25.5. I have been using these since January, no]ever seen rails. They have a few scratches on top sheet, nothing big just cosmetic. Base is in great shape! No core shots or even hige gashes! I would really like to sell just the skis, i might sell the skis and bindings together for right price. There 2009 mojo15's. Like I said though, there in great shape. Looking for about $400 shipped without bindings.
