Fits perfectly. I'm a size 9.5 in a regular width with a wide forefoot and they fit like a glove. I ordered size 9.5 euro 43.5 and they are just right. The material is excellent and they feel great without socks. Time will tell how durable they will be, but I'm impressed. The best part is that the color and leather make them look good with everything so you can go out without having flashy neon shoes lol. Highly recommended.
