I wear mucks more then almost anything. Work, hunting, trials training. Non stop. As a contractor/ carpenter, I beat the heck out of them. Just wore a hole in one after 4 years of the most abuse your going to give a boot. And It was when I was roofing. On my knees with my toes bent bad, the boot cracked on that bend just on the side above the toes. More of a older rubber issue and below zero. They lost a little flexibility after 4-5 years but not to bad till its real cold. I bought 2 pair the same. The other pair I never used on the roof, they are still going strong. Little slippery when you wear off the tread. I would Highly recommend muck boots. They don't make a finer boot in that niche, the muck. And no one on earth has abused them more then me LOL. I have arch issues and get sore feet from many shoes and boots. Not with my mucks. Why I wear them for so many other things.
