I bought size 4 for a little boy just turning 1 year old, hoping that  the shoes would be a little big and last him longer. It was small by a lot.  It looked like it would fit a a child of 6 or 7 month old .  The shoes are well made not too wide, almost for a child with long and thinner feet.  Soft and does not have a lot of support.  Good for a child just standing or balancing on his feet, but not really walking yet.  The Velcro is nice to avoid the child taking the shoes off and losing it.  Shoes were so nice that even though they were not cheap in cost, I kept them for a gift to another younger child in the future.  If you want to buy these a would suggest buying 2 or 3 size bigger than you need. Hope this helps.
