SUPER warm. Used these in Montana when it's -40 out. Size listed is 8 however these are more like a 7.5, especially with the insole - it's really thick (but removable) - I have kind of narrow feet and it was too much for me. Excellent used condition. Please see photos for measurements and feel free to leave a comment with any questions! comes from a smoke free, dog friendly home 🐾✌🏼
