I'm trying to find some winter boots for L. Our winters are long and cold and snowy.

Has anyone had any experience with these boots? What is the sizing like? L has pretty tiny feet for being 14 months. I think right now he's in a size 3 shoe. From what I can tell on their website, I *think* he should be getting the size for 6 - 12 months old, but that just seems SO SMALL. I want to make sure they last over the winter, but I also want to make sure he can walk in them.

Anyone with knowledge on these boots would be awesome!
