0 but Im glad I have one lying around. Materials are ok. They are very comfortable though, nothing pinches and they arent too wide or narrow. She can do it herself. I wasn?t expecting the plastic + fabric construction, however it still looks sleek and solid. Excellent waterproof sandal for an active toddler. After the first one; I was extremely careful while removing the styrofoam, but it didnt matter, there were still bits stick all over the shelf, the hooks, me, the floor, EVERYWHERE. Cant recommend them highly enough. Ive had these for a couple weeks now and I love them. They ARE too bright to allow them to be on all night in a bedroom.
