I am now on my 3rd or 4th pair of this boot. They last linger and are more comfortable than any other boot that I have ever worn. Buy your exact size and be prepared to have to break them in for a little bit, but after the break in process they fit perfect. I am a big guy so not many boots work for me. These even after 12 plus hour work days don't hurt my feet. I won't buy anything else. Great boot!
