This is my second pair of these shoes. They look a little nuts at first (a little big) but they are actually awesome. I love the convenience of slip ons. I love the renewable nature of the materials used. The only trick is to get the right size. I wear 13 in Adidas and 14 in Nike so I went 14 because another review said go big. And the 14 was perfect. So I would say lean to the larger side of your shoe size spectrum. They are quite comfortable also.
