KEEN made a piece last year called the Banff. If you're willing to go the way of a shoe in your creek boat as opposed to a bootie style like a Tokatee, this is a great option. Closed mesh - keeps sand & stuff out. Totally waterproof material so it holds no water with the exception of the neoprene-like sock liner. Built like a trail shoe and a little sticky rubber thrown in on the bottom. I actually found it to be warm enough without a neoprene sock, though often I'd add one just for added comfort. It's great for hiking and portages.
The downsize is if you have bigger feet than about an 11 or 11.5. You may run into fit issues inside your boat, depending on what boat you're in I suppose.
You can find them in a few retail stores still as well as on-line.
I hear you guys though. I'd love to see something Tokatee style again.
They've been floating around Nike outlet stores the last 6-8 months for $30
here's on place I found the Banff on-line
