Hellobee Boards

We live in the northeast but definitely get a lot of rain/snow. We've been doing unlined rubber rain boots (I like any kind that has those loops to help get them on) and the kids snow boots from llbean. The llbean ones we have have removable wool inserts that keep lo really warm. I'll use those for a rainy day if it's cold but it's nice to have unlined rubber boots for splashing around in warmer weather.

Also on team Hunters in Oregon.

I'm in Portland and my 2 year old he bogs last fall/winter. They worked great and we could layer socks for colder days if we needed to! They lasted all fall & winter and even into early spring. Totally worth it.
ETA we got an unusual amount of snow this past winter and they were great for that too!

Welcome to the Seattle area! we've usually done cheap boots from Target but they usually break down after about six months or so. My mom gifted us hunter boots for the girls and they've been awesome. Really great quality and I think they will stand up to being passed down between the three girls.

Welcome to Seattle! My DD currently has a pair of Hatley rain boots and raincoat to match, and she loves them. They run big so there's plenty of space for thick socks if necessary. But like others have said, it doesn't get that cold here -- usually low to mid 40s in the winter and maybe a handful of snowy days. Of course, if you plan to go to the mountains in the winter, snow boots would be necessary, but not really in any of the lower-lying areas.
