Danskos are so expensive in the store, so I was very happy to find this shoe at a great price.  Originally bought a size 38, but it was snug.  I wear an 8 in a dress shoe and an 8.5 in a tennis shoe, so now I know that I'm a 39 in a clog.  Because the toe is rubber, there is no give - buy the bigger size.  Luckily, there was free return shipping on the smaller pair.
