1. These boots are extra warm for low tempretures. Believe me, our winters are very cold.
2. They are really very comfortable, very easy to put on and out without any difficulties, zippers, clousures and so on.
3. Sizing is ok, I normally wear 10,5 on boots and 11 feets me perfectly leaving some free space for extra convinience.
4. Waterproof, it is really so - checked for two months.
All in all I highly recommend these boots for those who want Warm Comfortable boots you can jump in and go to play snowballs with your children for hours on very cold weather.
