These are, by far, the best shoes that you can buy for your newly walking or already pro walker. They do so well for my baby that this is the second pair and I will be buying a third. They are super comfy for them. They walk so well it's as if they don't even have shoes on. My daughter always pulls her shoes off, but these she doesn't even mess with. The strap is velcro and can tighten so well that even if the shoes are too big, their little feet do not move around in the shoe. They also do not leave any marks on their skin if you do have to tighten them a lot. I absolutely recommend these shoes if you are thinking of buying them.
