In the winter BHA issue there was an article from a guy talking about how he likes to hunt in his Crocs. I wouldn't go so far as to say I'm ready to toss out boots, but his comments about Croccs, quick dry pants with spares and neoprene socks as an alternative to hip boots or waders was interesting. I think the downfall would be really cold water. Unless you can find thigh high neoprene socks. I have only found knee high. You could couple then with neoprene pants, but I'm not sure how waterproof that combo would be.
