I love these boots. They are very warm. I have trouble with boots that go up over my ankle but these are great. They are very comfortable. I normally wear a 9 but after reading reviews and measuring my foot according to the sizing chart I ordered a 10. They are very comfortable with one pair of socks on but there is enough room to wear 2 pairs. They have good tread on the bottom. Great fit, great warmth, easy to get on and off, great boot.
