I spent a few weeks researching, and comparing models before I finally decided to purchase these. Ultimately I wanted a pair that was comfortable and waterproof as the winters in the northeast can be unforgiving. Oddly enough, I've had these for some months now and the zipper on one of them has faltered twice and is in need of repair. I wear them on a regular basis but as I work in a retail store selling computers, and NOT actually using this in the type of "rugged" terrain they're intended for I'm unpleasantly surprised that there's been any issue at all. I must say though, I've never found boots of any sort to be comfortable until I broke these in. They hug the feet similar to athletic shoes and are very light and flexible. I would certainly consider purchasing another pair in the future although I might think twice about any model that has a zipper.
