I've had better luck with Kennetrek than Meindl, Danner, and other brands I've used. I treat them a couple times before a wet hunt though. I treat them first in August during the heat. I use Kennetrek wax and set them out in the sun all day on the deck. I bring them in at night to avoid dew and put them out again the next day with more wax if they will take more. When it won't soak up anymore I quit. I then wear them on wet conditioning hikes until right before the hunt and treat them again. When I do conditioning hikes in dry grass I wear my Salomon 4D boots to save wear on the Kennetreks.
For caribou I used the Crispi Hiland Pro boots with the built-in gaiter. They kept me dry for a week of the wettest conditions I'll probably ever hunt in. If I'm headed on a hunt where I'd consider muck boots I'd use them again. Muck boots just don't work for me if I'm hiking a lot. I need some ankle support, and even with good insoles they are hard on my feet over time. I fought plantar fasciitis for a year after wearing muck boots for work to much on a reall wet fall. I never want to do that again.
