Boots are very comfortable, however a little deceptive on the sizing. I am not familiar with the width of my foot as I usually get standard sizes, and they all fit, but for some reason I had to get the wide version of this boot. Nonetheless, exchange was seemless and I received my replacement pair before I could even get a chance to send the small ones out! Non-slip, very waterproof, very comfortable, takes a while to get used to the high-cut as the first few days it pinched my shin, but after awhile you get used to it. The only gripe I have is that if you wear them for more than 12 hours a day like I often times do, it isn't very breathable and your socks can become very damp. No smell, however, but can be a problem if you have sensitive feet.
