My daughter is 3 years and 8 months normally she is very tall for her age 42 in and she use 8m toddler size shoes but some shoes are 8m and are tight so I buy 9m they are a little big but still fit on her and she walk well with those. Also she will grow so fast so I think that are very good. I like that are open for smells and also protect her toes  when she run .
