I usually wear 7.5 - 8 therefore I ordered an 8. They fit fine, especially with socks. Not too small or too big, perfect. Like other reviews they squeak a little when walking swiftly on hospital floors however not an obnoxious squeak. I happened to notice it at the end of a 13 hr shift so, because of noticing it so late in the day, I realized the sound wasn't that obvious. Another plus, they are light weight which is great after a long day on your feet. Glad I bought them. Cute pattern, got a lot of compliments and the price isn't excessive like some nursing shoes..
