These are good shoes. I wear size 12 but my foot is about 11 3/4. These fit perfectly. I have a different pair of Sperry slip ons and that 12 fits more like a 13. First reaction when putting them on was that they were too narrow but after I got my feet in and moved around in them they fit fine, and better without socks. Havn't used them yet, we will see how well they hold up compared to other reviewers comments
