I've done everything in these shoes: hiking in Colorado, canoeing in Virginia, November steelhead fishing in New York, Walleye fishing on Lake Erie. They are by far the most maintenance-free shoe I've ever owned. They are definitely waterproof, and the synthetic material actually kept my wet feet warm in 40-degree temperatures (don't ask me how, but I was surprised).
Two problems with these shoes:
1. too narrow. I got a blister the first hike with these shoes, and my right little toe tends to rub often when I wear them. I even got a 1/2 size too large.
2. shoestrings are junk. The tubular shoestrings will NOT stay tied. I bought a $2 pair of flat strings and they've been fine.
I would recommend this shoe, but if you think you have wide feet, you better walk around in them first!
