It doesn't matter what the weather is like outside, my kid is going to want to run around in it. The only problem is that most winter boots aren't made like sneakers, so that they don't have the same kind of grip and you can't run in them the same way. These boots though, feel more like heavy duty tennis shoes. They seem waterproof, but I haven't been able to test that out yet. I can tell you that they feel especially well made and my kid says they're comfortable. The grip at the bottom is going to help her stay running around until there's a foot of snow on the ground, and at that point I'm not letting her go outside, so it doesn't matter anyway. All in all, I like them. These are good boots, and I'm glad I got them.
