Like some others here, I found these to be poor quality shoes - not what I would have expected from Pediped. I bought these for my four-year-old and within a month the rubber treads were peeling off the bottom of the shoes. One of his teachers tried to tape them together so he could play without tripping. I've never had a problem with any of his other shoes disintegrating, so I have to assume it was the shoe, not his wear. Fortunately we were able to return them.
