Goretex is very comfortable and lightweight and seems to keep feet dry. I usually wear an American 11.5, these shoes are a 12 and fit perfectly. The biggest problem is that the outsole wears out incredibly quickly. With less than 60 miles of hiking in these boots, the front of the sole wears away almost completely. Mostly hiking in the Adirondacks/Northeast, mostly mud, with 20-mile hikes in Utah/Southern California.
