I wont opine on the camp shoes and whatnot, but for water shoes heres my .02
I just got Keen Gorge booties and they are pretty frickin sweet. I have only worn them twice, but they are definitely bomber so far. well built, adequately warm, room for my hydroskin socks, and I like how they open at the ankle, cinch down securely, and have good traction on the sole....and a wide footwidth like me. :] the sole is a little stiff for my playboat, they fit but kind of rolled my ankles in. but then i got them primarily for creeking and cold weather.
My other paddling shoes are NRS attack shoes.for warm weather months. for rafting i wear either chacos or my kayaking booties for cold water. NRS makes water sneakers that i have as well. other then Keen, 5.10s look really nice.
