If it isn't going to be cold, I use Xtratufs, which I've owned since my first fishing trip to Alaska, and have put up to 20 miles on them in a day hunting elk and turkeys in the wet, plus walking in wet snow when it is above zero. I always put insoles in them. Without long underwear(sorry, base layers), the 16 inchers rub my calves, so I use the 12 inchers.
I tried a pair of LaCrosse boots one turkey season while hunting alone, and my feet sweat and swelled enough during the day that I couldn't get the boots off. I finally sliced them down the side with a knife and burned them in the campfire. Tight at the ankle is good for walking, but has its drawbacks.
