I normally wear a 7.5 and wish they had 1/2 sizes because I went up a size and they are a little roomy. I feel a 7.5 would be perfect. I haven't tried them with super thick socks, but it would probably feel better. I live in Hailey, Idaho where we get a lot of snow and I played for a few hours outside the other day and my feet stayed warm and dry. (with thin socks) I love that they are super lightweight and very comfortable. I have seen a feather or two coming out, not a big deal. I was thinking about purchasing these but didn't get them until I saw another lady wearing them and she gave them great reviews and I'm glad I did.
