I have no idea why people have left 2 star reviews...I have been buying Pedipeds since my son learned to walk. These awesome shoes are super flexible, the quality is fantastic and the price very reasonable for what you get. My son is 5, his foot is size 12. The first pair ordered in 12.5-13, his toes were touching the ends already. We returned it and bought the 13-13.5 size, put the extra insole they provide you with and they fit PERFECTLY. When his feet grow more, we will just take out the extra insole and I won't have to buy another pair of shoes right away. He also doesn't like his feet to get hot, we live in the desert and the last 2 days were 115* and 117* degrees. He wore the shoes at school all day and loved that they didn't make his feet hot and felt so good when running also. FYI, I know it's not easy to find great shoes as they get older but these are it.
