These shoes are slim fitting so you can order a full size larger than usual. I had to send my first pair back but it was easy. The new larger size was still a bit tight but I wore them all day boating in rough seas and they were very comfortable.
Pros
The shoes didn't fit, the return was easy and quick. Will definitely deal with them again.
Cons
Those shoes were damn small. They were marked wide and I couldn't put my toe in! I (sent them back but what a pain.
