Where did you buy those 2007 hails for $50? I just bought 2007 Hails (sandstorm) for $105 and the place I bought it from will price match. I was also wondering the same thing by the way. I am facing a choice between this years Rome Smith boot and the 2007 Burton Hail and am really struggling the with decision because I don't know how old the technology in the Burton Hail is.
I bought them off ebay for $48 total. They were only used once. I got them 2 days ago, and there is not one single sign of wear. I'm very happy with my purchase. They even smell new still! For a newbie, I think these are the perfect starter boots. They are very comfortable.
