These snow boots are made extremely well. They are very well insulated and keep your feet warm in the coldest of climates. They even come with their own separate foot insulators that wrap around your foot. If you don't want them you can simply take them out. They are extremely comfortable and easy to walk in. I use them while sledding and hiking through the snow and I have never had cold feet with them. Highly recommend. Also, order 1 size bigger as these boots run 1 size small
