They're not as nice as the Khombu Abby boots I have, but they are decent. They fit well & snug on thin calves. They give you a little extra height which is nice. Keep my feet warm. I've read other reviews saying the zipper was an issue. I haven't had problems yet (knock on wood) but I am being extra gentle with the zipper when I use it. Comfortable for walking short distances, but not for being on your feet all day.
