I've gone through quite a few pairs of amphibious shoes in the last year. These are the best ones I've found so far.
North Face Padda

They are comfortable, durable, very light (22.7oz per pair in size 11.5), have good traction, and quick drying. I had a pair of the Techamphibians for a couple days before returning them because I didn't like the strap closure on the heel because it kept coming loose. These shoes are superior IMO.
What's your fishing / hiking shoe preference?
