Having at first ordered my usual size 7 I found them to be very wide fitting so I returned them and went a size down, a bit apprehensive regarding toe area. When they arrived I was grateful to know they fit like a pair of slippers! I have plenty of room, can move my toes around with ease so sorted! I would say they are wide fitting so I would advise trying a size down from your normal especially if you have narrow feet as I do. On wearing for 12hrs in a warehouse they are comfortable, however I have added insoles and slightly thicker socks for a bit more solid fit for me and to lessen the wide fitting issue. I find them very light weight, people have commented and asked about them, and work/security eye them suspiciously as they look like stylish trainers! Very happy with them.
