My son is 3yrs and he will still wears his Robeez at times. They are just to easy to get on and comfy for his. I also love the peddoodles. One thing our doc told us is that the sole of the shoe should be flexible. You are supposed to be able to touch the toe to the heel of the shoe. Does this make sense? Take the shoe and bend it in half and see how flexible it is. We have had and seen way to many accidents because little toddlers are in these thick soled shoes (sketchers etc.) and they can't walk in them.
