Really nice pair of boots.  Other reviewers are correct.  This boot runs about a size larger.  My Asics running shoes are size 10.5 4E, my Wolverine work boots are size 10M.  I ordered these in a 9.5 W and after receiving them, I could have easily worn a 9, but the 9.5 will give me enough room to wear thicker socks during the winter.  Great price too! Was originally looking at them on Zappos, but they were $165!!!
