I wear a 7.5 but because these only come in whole sizes I would normally order an 8.  My previous shoes in this style fit me until I washed them and after the dryer they were so tight I could no longer get them on my feet so I was a bit wary of what might happen to these after they go through the wash.

The other reviews I read said these ran small so I ordered a size up and got a 9. The shoes fit right now but are a bit big, but I'm happy with them for now and I also am comfortable that once they make it through the washer and dryer they'll still be as awesome as they are today.

Crocs are my very favorite shoes.  I have a really gimpy foot following several surgeries and Crocs are about the only thing I can stand in and walk in.  The comfort is off the charts and I love that they come in so many styles and varieties!
