RoundRiver: "I have Boundary Boots and like them for what they are. For regular canoe tripping with numerous and especially longer portages I would not choose them for that type of trip. Instead:
Astral Rassler 2 paired with NRS Boundary Sock. Just get a size or two larger to fit the sock - I got one size larger. This is the best overall system I have found. I have a total of over 50 wilderness canoe trips, many of which are across all kinds of terrain (soil, mud, rock, underwater, bog, steep slopes, downed tree riddled, wetlands, lining river rapids, beaver dams, etc.) and I always wet foot. The tread does not look like much but it works very well.
And Astral’s customer service is excellent. I had pairs in the past that had started to unglue in a spot or two. I told the rep and they found that unacceptable and gave me a brand new pair each time. Note I shoe gooed the minor deglued spot and have kept using them, saving the new pair."
that gave me an idea - i've got the patagonia lightweight wading boots that I really like. I could just run those with a waterproof sock or neoprene sock.
