Wet foot or dry foot?  For my son and I's canoe trip in Atikaki Park, MB we used the same approach as @OutsideInND (aka wet-foot). I was skeptical at first, but a good lightweight hiking boot (fast-draining w.removable footbeds) and good quality synthetic socks was a great solution. We wore Merrell Moab Ventilators mid-top for ankle support (dropping your feet into ink-black water while dancing in/around bowling-ball sized rocks). They also performed very well on the portages, even when wet and carrying heavy/awkward loads on the Canadian Shield granite. No blisters or hotspots either. Just had to spend a little extra time to get them as dry as possible while in camp. Probably won't last much beyond 1 season of constant use is the main downside.
