I wear 10 1/2 in boots, shoes, etc. For example, in the Timberland Pro boots, a 10 1/2 is a perfect fit. When these arrived I was really impressed by the quality and details, plus the free extra laces. They look really durable and the soles are impressively wide and thick. However, once they were on and laced, I had a surprise - these were huge. The 10 1/2 D/standard width were more like 12 EE. When I walked in them, the part of the boot that "hinges" when you walk pinched the heck out of my feet. I assume that's due to the size. From all appearances these are a well thought out, high-quality product. I replaced them with a different make only because I knew the size that fit me, and did not want to ship these back and forth until I found a good fit. Amazon's return policy is fantastic, but did not want to spend several attempts and a couple of weeks finding the correct fit.
