These are great shoes for your baby, we have twins and have been using them for some time.
We lost one shoe the other day, it fell off.

You must pay attention when lifting up the baby in public places as the shoe tend to slip off easily, and yes were the rite size we bought a size smaller and a size bigger and they just tend to slip off.

But I do recommend them as they are made well and stay on as long as your toddler is standing in them.
