I listened to most reviewers who said to order a size up (I normally wear an 8.5-9 and ordered a 10, wich I was very nervous about) and they fit perfectly! My right foot is a little bit smaller than my left from shattering the growth plate when I was younger, so that boot is a little bit bigger, but it's definitely not a big difference. I do love that there is enough room in each boot for thick socks! When I first got the boot (the day after ordering them - make sure you are there to sign for them if you choose this shipping method), they were pretty tight around the leg. I'm 7 months pregnant, so it could have been the swelling, but they didn't fit all the way up my leg. My sister has skinnier legs than I do (and is only 3 months pregnant) and they fit her perfectly. Another reviewer stated that you can't roll the boot down... it's definitely not an easy task, but it is doable - the inside tags just stick out, which doesn't bother me because the lining is white and so are the tags. They aren't that noticeable. This is what I had to do to avoid the circulation in my legs from being cut off during the last few months of my pregnancy. I LOVE the sand color, and I'm extremely happy with the product. I've never owned a pair of uggs, but for this price, I don't think I ever will. They are extremely comfortable and warm (after a good 20 minutes I get too hot wearing them)! I love that the soles are so thick and have great traction. I didn't want anything too thin for fear that I might slip and fall. I ordered another pair in the chestnut color, but have yet to get them due to the fact that I wasn't here to sign for them when the delivery guy originally came. If they are anything like the sand colored ones, I'm sure I will love them just as much!
