I choose a five because these are very cute, can be dressed up or down, and my daughter has not figured out how to get them off. she wears a size 3 so there is some growing room, but they are not sloppy looking. she gets good traction when she stands in her exersaucer and when she wants to practice her standing on the floor. all in all i love robeez shoes and would recommend them to any parent. there are cheaper versions, but you get what you pay for.
