Q: Comfortable boots that are indeed water proof and actually do breathe. They seem to work well for the winter wearing anything from cotton socks to solar socks depending on the outside temperatures. It should be noted that they do not have a slip resistance sole so they can be slippery on smooth wet surfaces. I haven't had a chance to use them in warmer weather to see fully how well they breathe. For the price they are a very good buy.
A:
Positive
