I just bought these Sorel boots from Amazon last week and I am in love! It took me 2 winters to try to find winter snow boots that are comfortable and warm at the same time. They are comfy like Uggs but they are also waterproof. They have this squishy base that kind of feels like the gel-like base that some sneakers have. Love them!
