Bought these for my daughter, now I wish I would have gotten a pair for myself.  I'd bought her a pair in black last year which she loves and was happy to get a second color.  I have a pair in black that I purchased for myself.  They seem to run a little large.  I generally wear a 7.5/8.  I purchased the 8 and they are a bit large.  Probably would go with the 7 if I had to do it again but I decided to just layer on socks instead of returning.
