I have used the Alpha 4x snake boots for the last couple years for early season deer and turkeys. As mentioned already, they are ok. Then keep my feet and pants dry and are snakeproof (supposedlly). They are ok for normal walking, but not for hiking any distance, and they're hot. They've held up great and are waterproof and I don't hike a lot, so they work for me. When they wear out though, I'll likely switch to lace up leather boots of some sort. They aren't super comfortable, and are a bigger looser fit.
I've been looking at new boots, but I want snake boots and I want to be able to tuck my pants down in my boots so they don't get soaked, but have yet to find anything I like so far that didn't cost an arm and a leg.
