I usually wear 10-10.5 shoes (US). After reading reviews, I bought a 9.5, as many people say that these boots fit large. They fit perfectly for the first few hours, then became to big and caused bleeding on my heels. I exchanged them for 9 ( a full size down). Don't get discouraged; it took at least 2 weeks of mild pain until the leather stretched. Now, they are extremely comfortable. My recommendation is to go one full size down. They look good, timeless, and solid. I hope to wear them for many years.
