I have worn these boots all day - both to work and on dog walks in deep snow - for about 4 days since I got them, and I love them! I have a narrow size 8.5 foot and the 8 is a perfect fit, maybe even a bit big. I also have muscular calves and, while the boot top is tight, I loosened the top strap and can wear jeans tucked into the boots. The sole is super grippy. The boots are not insulated but are lined, and they keep my feet and ankles warm enough even in sub-freezing weather. They look great with skirts or with pants. I got the brown color; within the first hour or two I had scuffed the top of one boot but now I can't even tell because the nap on the boots hides marks very well.
