I've spent many 18-24 hour days on my buddy's Pilothouse hunting for bluefin cows on both rough and smooth conditions. Used to use Xtratuff boots. But if the seas are rough, I'd get lots of foot pain from slamming on the swells, especially on the big-toe. These Shimano boots are hands-down the most comfortable boots I've used! The padding on the bottom is super thick and has space underneath, so if you get splashed and water gets in, your feet above the water and stay dry (for the most part). I HIGHLY recommend trying them out. The only downside is that they run a little bit on the large size and they don't offer half-sizes. But I don't mind the extra room. Never felt like they were going to fall off when running up to the bow or hopping up on the roof with the binos to check for birds
