I don't have a ton of good info for you, but I'd say that prevention is the best method. I did not put a wax treatment on my kenetreks prior to my September WY hunt as I expected it to be really dry. Boy was I wrong. It dumped rain (or snow) on us 9 out of 11 days. My feet stayed wet. I've never had blisters before this hunt, but I grew a nasty pair of them on the back of both heels after the first day moving up steep slopes in those heavy wet boots. Had to fight that heel pain the rest of the 10 days and it sucked big time.
I DO have a stove in my Tut, but I never got my boots dry. I'd stick them right below/beside the stove body but the fire just doesn't last long enough to dry them out and I was usually asleep pretty fast. I guess if you sat out for a half/whole day of hunting just burning wood in your tent then you could get them dry; but without a good water treatment they are just going to be wet again within an hour of leaving the tent.
One evening I was getting desperate and I decided to put them next to the campfire to dry them out. Mistake. Got them way, way too hot and ended up having to send them in for repairs. Cooked the glue in one sole. ruined the rand on the other one. So don't do that. They get hot FAST.
Combine a good boot treatment with sock changes and you should be good to go for normal hunting scenarios. I changed socks around mid day, then again back at camp in the evenings. That rotation helped a good bit.
