These Uggs are so comfortable, keep your feet warm, look awesome not big clod hopper looking! Lol! I wear a size 6 m but I went up a 1/2 size and they are just right for me. I wear them with thin socks. If you have a wide foot then I don't think these are for you. They are a little tight and hard to get on the first couple of times but after that they are great! I wore these for over 10 hrs. Awesome shoes! I have gotten a lot of compliments on these shoes. Thanks Amazon.com for offering great products!
