Input: These boots are some of the most comfortable that I've ever worn. Even after being on my feet for more than 6 hours my feet felt good. The boots are very warm which is kind of a draw back since I live in Las Vegas. However, after a day of work I was pleasantly surprised to find my socks were still dry. These would probably be best suited for cold climate hiking, but they work pretty good in the desert. Well worth the money.
Output:
Positive
