Like Preacher, I typically wear 16" LL Bean Hunting Boots. However, three years ago on a late Oct./early Nov. trip I wore a pair of lightweight Muck Boots and they worked great. Very good support, warm, 100% waterproof, no laces to collect mud, they wash off easily and you can tuck your pants inside to keep them from getting wet. Even though they have a very snug fit around the ankle, the one thing I don't know is how well they'll stay on in a boot sucking mud pit. Depending on the forecast I may wear them again on our spring trip in a few weeks. If I do, and considering our trip will involve several nasty, muddy portages, I could have that answer really soon.
