Comfortable, durable, waterproof, and Vibram soles. I've served under USASOC, so my feet have had a lot of time in boots. They meet and exceed expectations for footwear. Only drawback would be, and this is only common sense...waterproof unless you step into calf high water for more than a few seconds. Boots that keep water out have no drain ports, so they also keep water in. So if you are going to be slogging around in a swamp or crossing a river, then expect to get water logged. Take em' off, dump em' out and you're no worse off than if you had jungle boots on. Good to go, if your feet are conditioned.
