These do run large as lots of people have already stated. I normally wear an 8.5 in everything and ordered an 8 and they fit perfectly. I do wear them with socks because....gross. I know these have been popular for like 15 years now but this was my first pair. I just generally don't like to spend a lot of money on myself. After actually trying on a pair somewhere I figured out what all the fuss was about. They are SO comfortable!! I got these about a month before it was really cold enough to wear them and was stoked the first time the weather said we had cold weather coming so I could wear them. Toasty warm feet for sure. Was torn between getting the bows or getting the buttons but I'm glad I chose the bows. So cute.
