I love these shoes for my 18 month old. The length of his feet are about a size 4 (18m for these shoes), but his feet are a little chubby, so some brands have been a challenge to fit comfortably. Hes only just starting to walk and still a little unstable, so the lightweight nature of these shoes are perfect. Hes gone on a few walks in the park and they have held up well. They are easy to get on and off, and so cute.
