Have I told you about Swagbooties? I bought Wesley a pair (in houndstooth) of these a few months ago and they are PERFECTION. They are easy to put on, washable, you can choose the color of the sole, I'm assuming they are comfortable (he hasn't said otherwise;)). They are still in really good condition which means they've survived many trips back and forth to daycare. I'm about to buy a couple more pairs for his little growing feet. They have such soft soles so I think that learning to walk would be nice in them. These definitely top my list of recommendations for babies and toddlers.
P.S. I'm in the boy zone, but they have a lot of great girl options too..
