This is my go to boot. I go through a pair at least a pair a year (harsh conditions). A good coating of snow seal when new makes them waterproof for the most part. I usually wait until there is a great sale and will buy a couple pair. No boot lasts forever.
My husband is very hard on his work boots, as a farmer, he goes through a pair every year, some don't even make the season. He bought this pair of boots in 2016 and is still wearing them. He could probably get another year out of them, but as they are sale, I am buying a new pair, so he can retire this. This has never happened with any other boots.
