My wife and I both have a pair. We have had no problems with them and they are comfortable. I caught a barbed wire fence with mine and it tore the upper a little but not all the way through. No more than any other neoprene. Their website is
www.muckbootcompany.com At the time I couldnt get it to work, maybe you will have better luck. So, light comfortable, and hold up to my abuse, I would recommend them. Also the sole that is on mine doesnt cake up with mud that bad. Hope this helps.
