First of all let me say these are super cute to be black rain boots, the brown buckle gives it a little something extra, and they don't make my feet feel like clown feet lol I normally wear an 8 and thats what I ordered, they are actually a little big. Im sure they will fit with thick winter socks though! I only gave 4 stars because 1 boot does have a small tear in the rubber, but its not significant enough to send them back.
