My Cabela's Meindel Perfekts are still fully waterproof. I want to say this is their 5th or 6 season. They've been outstanding boots.
I have the Danner Pronghorns gore-tex as well but they are the camo version with half canvas... comfort wise they are great, waterproof they are not. Even with the Gore-Tex, I got one good season out of them before they started leaking.
Ariats all day. I swear by them. They are expensive but mine have lasted over 4 years so far working on the farm, hunting, hiking. I wear them for everything. They are very comfortable and very durable. They also are still waterproof after 4 years.
