I know what you mean about everything being unstable in a flooded swamp.I usually just take to the water when that happens.I would rather walk down a chest deep ditch then try to pull a balancing act and go in head first.If the bottom isn't muck then the deeper water usually has a more stable bottom,problem is when you hit muck it's either revert back to trying to stay out of it or just belly down and crawl
Mudder boots look like they could handle the muck well but they would tear up so much plant life in a cedar swamp I think I"d save them for slat marsh mud flats,besides in a swamp they would probably get you hurt.
