The ski shop on Steamboat talked me into buying smaller snowboard boots as they fit better - tighter = more control - resulting in blisters so bad I've missed days of skiing. I bought this orthopedic felt for my next ski trip and it helped a lot. Distributes the friction over a large area and not directly on the skin, so I no longer get blisters. Highly recommended. My only complaint is that the adhesive backing is very difficult to remove, I always waste time fiddling with it.
