I recently went to Alaska to use the boots and they worked great! Got great traction and it kept my feet warm even at -30 when I was outside at night looking at the northern lights. Also while knee deep in snow I had no problems. I would agree with the other posters and get a least 1 size bigger, I usually wear size 12 so I got a 14 to compensate for the multiple layers of socks and it worked great. I would say a great buy.
