I have a plain medium foot. A medium width always fit but not these. I would have needed a narrow which I never bought in my life and I an 60 yrs. They are a very nice looking sandal and I would imagine if not to wide would be very comfortable. However, I just put on and walked around the house and they were not staying put. Back in box they went. Also, I'm stuck with them and guess will donate them because IT'S ON MY to spend more money to exchange for a narrow size especially due to leather does expand. Company makes you pay for this. Oh well, live and learn.
