Red Head Bayou zip up snake boots in full APG. They are by far the most comfortable boots I've ever owned. They feel just like a good pair of Nike Air sneakers to me. Two seasons on them so far and they haven't sprung a leak yet.
I used to only wear Lacrosse rubber boots, but they made my feet sweat too much and weren't the most comfy for long walks. I looked at Rocky snake boots, but everyone I know that has them said they leaked.
