This is the first time we buy Chaco shoes. My child just started using size 13, and his feet are of normal width. I had ordered the size 13 of the outcross 2 water shoe (dark moss) and they were very small: they looked 2 sizes too small. Since they seemed very comfortable and perfect to be used at the daycare, where they ask for closed toes shoes for the summer activities, I ordered a size 1. They fit well, and there is room for my child to wear them for a while. So size up! Thanks to the seller for making the exchange!
