This boot Is Super Comfy right out of the box. I recommend going a half size down from your regular shoe size. I usually wear a 10 in running shoes and casual shoes. so the 9.5 was a perfect fit! I have already tested the 2010 version of this boot and it is even better!I love the inside-out lacing. you can tighten the lacing that holds your ankle down without un-doing the outside laces. THE HEEL HOLD IS THE BEST ON THE MARKET!My Only Complaint is that overall, the boot is too soft for all mountain use. This is deffinately a Freestyle jumps and rails and boxes kind of boot.What I have done with mine, is i have put a ton of foward lean on my bindings(Burton Missions), and the boot conforms perfectly into the bindings so that i get a ton of response when transitioning from edge to edge!Ask me a question on here and i'll try to answer it.
