I've been dreaming about these for a few years now.. So very glad I finally got a pair! They are very warm and toasty, My feet were totally comfortable at -20F. I am able to drive a manual transmission vehicle without too much trouble, if I'm not sloppy about my foot placement. It's not uncomfortable to drive in them. I love that I can just slip them on and head out the door. I wish the size ranges were a little closer together, they're a little sloppy, but that definitely emphasizes the slipper-comfy feel. They're super cute, and I've gotten lots of positive comments (I've got the bright red ones). Definitely the best winter boot I've found. Our snow is fairly dry, so I don't know how they'd do in really wet conditions, but the rubberier(?) coated bottom part would probably keep most of the moisture at bay. I love them!
