The Teva Jordanelle's are amazingly warm, waterproof and light weight. My family and I went to a ski hill for Christmas and I basically lived in them. It snowed the entire time so I spent a lot of hours trudging through several feet of snow, and my feet never felt even remotely damp or cold.
One of the most impressive things I've noticed about these is that they have really good tread. They feel really secure and slip-proof when you're walking on ice, which makes them perfect for every day wear.
I got these boots without trying them on, so I was a bit nervous about the fit. My feet are fairly wide with an average arch height. They fit me well, so they seem to be true to their stated size. The only negative thing I noticed was that the back of the ankle was bit stiff at first. It would be a good idea to wear them around the house for a bit before heading out for a full day in them, as they're perfect after a couple wears.
I'm really happy with these and would definitely recommend them. They're hands-down the best snow boots I've ever had!
