Depends where I am, and when. I canoe mostly in LA year round, and in the Adirondacks anywhere from June-October, depending on when I get my vacation. If the water's too cold, I will actually carry and wear a pair of knee-hi rubber boots. That's October in NY, NOV-FEB here in LA. The rest of the time, here in LA, I wear a pair of cheap walmart water-shoes, with the rubber sole and mesh uppers. In NY, it's usually barefoot (no snakes or cypress knees). It's pretty quick to change back into dry socks and shoes once you're ashore.
I sometimes wear wool socks with the water shoes, and that helps a lot with clamminess, even in summer, and keeps them from getting sunburned. Two pairs is about all you need for a week, three if you insist on having something dry, but they dry out quick enough if you have the right shoes to go with them. Damp feet while camping/canoeing is the norm, for me anyway... wool keeps it manageable, warm, and fun. I gave up on 'dry feet all the time' a long time ago. just not worth the bother.
