Were a little big BUT I'm not sure if that was an error in measuring on my part. The good news is, baby will be able to wear them next summer as well hopefully. We needed water shoes for water play at day care and they served that purpose. He will only wear them one or two times at the end of the summer season. I like the adjustable feature, they were easy to get on his foot. They also seem to be made well (only used them once). Decent product for a decent price.
