Order one size definitely bigger! I ordered it a size bigger and he's still pretty tight. Wear after a few times he will pleasantly. Otherwise it is a very fitting Abeler shoe. I used it to work and for that he is a bit clunky. Next time I would buy a running shoe in the store. If you walk through tall, wet grass is a little wet socks by the "breathing material" at the top. But otherwise he is good waterproof. Go a good choice for walking.
