I'm looking to buy rain boots for LO2, who turns 1 in a couple of weeks. He's been walking for about a month and they're predicting an El NiƱo year, so hopefully it's really wet! That being said, he still trips over his robeez when he walks. Any suggestions on what brands might be good? Most of them seem to have a stiff sole. Croc rain boots start at size 6, and he's probably a size 5 (and that's with room to grow). Any other suggestions?
