I bought it for my nephew that recently started to walk. He has a high arch foot. He unable to wear certain shoes because the top of his foot will not close. These are perfect for him bc its velcro. The squeeze feature is a plus, hes able to jump up and down with them and enjoy the sound of them. The dog would chase him around in the beginning. Love that the feature can also be turned off after a long day. He was  16 months at the time, I bought him a size 5 and it fit him perfectly.
