This is my fourth pair of boat shoes but I must say they fit much differently than my others. I first ordered a size 9 but when they arrived I could tell by looking at them that they were too big! I tried them on and they slipped off my ankles and made my feet look huge. I usually wear a 9.5 but always order a 9 in Sperry's and they fit perfect. I sold these to a friend and purchased a 8.5 (for $30 more dollars than my first pair) and they fit better, but now seem really tight. Not sure how there could be such a size difference with .5 difference! Anyways, they are cute and got here within 2 days which was awesome. They are durable and so adorable. Love Sperry Topsiders, just be aware of the size difference before you purchase!
