Get something with Neoprene! The material is so incredibly warm but also light at the same time. I have a pair of Bogs brand neoprene boots that I wear for almost everything in the winter because they're so warm and toasty. I have literally fallen through ice on the creek in 15 degrees Fahrenheit weather and filled my boots with ice water only to have the water in my boots warm up and be almost comfortable again before I got back to the house. I can't recommend them enough, though you should probably find a brand with similar construction but intended for horse riding if you don't intend to be wearing them for everything else (like I do).
I am here to learn! :)
