I ordered my regular size. They fit fine. I could have probably gone up a half size and still been ok, but these are extremely comfortable. If you have a wide foot, these probably are not for you. I feel like the way they are made would be difficult for a wide foot. However, I love these shoes! As a teacher who is on a concrete floor all day, these keep my feet from hurting so bad at the end of the day. My friend told me it would take a day or two to get used to them, but I didn’t have any trouble adjusting. I am wearing them every day now, so I am anxious to see how long they hold up!
