I have a pair of Korkers (the Torrent), and while they work great, as mentioned, since they're low-top, they collect a bunch more debris than you would otherwise. I haven't worn them in over a year, if that tells you anything. If you're hiking long distances though, they'd probably be great. I've since started just using a pair of cabelas wading boots (sized for my feet, not for my feet plus neoprene)...either that, or wear the waist-high waders...
