Ben,
A few final thoughts, have you considered dry footing it? I really like the Chota Muklucks. The tread is not that aggressive so if your not sure footed you might consider something else. Prouboy was looking into a "grippy" rubber sole addition to his Mukluks. Pretty hi-tech, the material was something like the teva spider sole water shoes ( I think that was the name :question........impressive traction indeed....I have a pair).

After my first wet boot experience I have yet to "wet boot" it again. My feet got soft wetfooting it and bingo, I was done.....1st day. Since then I've used the Chota Mucklucks with a liner sock and hiking sock in combination. Even though I still mange to get a soaker now and again no more blisters. Very comfy, even in the boat.

Lastly, I always carry moleskin in my first aid kit. Not sure how it would do in a wet boot environment though.
