I work in mountain operations at a ski area in the Rocky Mountains, and have used these boots for 4 seasons. Sometimes I work in my ski/snowboard boots, sometimes I work in my Muck boots. But on average, I work 4 days a week for 6 months of the year in deep snow and cold conditions. I’ve put these through the wringer and I recommend them. Just a couple heads up: they’re waterproof but make my feet sweat quite a bit, so as long as I stay moving, my feet stay warm. If I have to stand still for a long time in conditions around 15F or colder, my feet will get cold (and I don’t run cold). I noticed last year that my heel has completely rubbed through the lining straight to rubber, and water seeps through. I’d say for how much I use these, that’s not an indication of poor construction. My only complaint is that I wish they were even warmer.

Boots never came had to get a refund. When they refunded me they only gave me back the cost of the boots but still charged me the sales tax!!

Really like like these boots.my first pair lasted 3 years. Figured these new ones will last just as long. And they do keep your feet warm at -60 wind chill.

Have had these for 1.5 years and love them for winter dog walks. Just wore them on a dog walk and had to cross a stream- they immediate;y leaked into the boot around the seams where the rubber meets the neoprene. They still look brand new and I've never worn them in water as they are so warm, I don't use them in shoulder seasons. No rips, tears or holes to be seen. Extremely disappointed I could not wear these while river fishing. Would love to hear from Muck about this. Anyone else with this issue?
