I don't wear them but I just saw that Cabelas has some rubber snake proof boots on sale and now I'm debating getting a pair. I've never been afraid of snakes, poisonous or not, that said, I AM VERY CAUTIOUS OF WEAR I PUT MY HANDS, FEET, OR ANYTHING ELSE. I usually spot the snake before I get within 2 or 3 feet of it. The only time I get nervous is going through high grass or palmetto's where I can't see the ground well. My experience has been that a rattler won't strike unless he is poked, prodded, stepped on etc. Cotton mouths are another story, they will strike unprovoked, and will give chase, but not all the time. I've only came across 2 or thrre copperheads and they were not aggressive. The most nervous I've ever been was 5 years ago in July, I was sitting in a chair back by my pond with my grandfather fishing and a cottonmouth came from behind me, crawled in between my feet when I saw it, flicking it's tongue on my left shoe, then crawling out about 5 feet from me and coiling up. I just sat still ,i.e. to scared to move, and let him get away from me before getting up. My grandfather was more scaried than me I believe, he told me I was crazy for just sitting there not moving. I believe that since the snake wasn't disturbed by me moving, it didn't feel threatened.
so, as I said before, I've never wore them, but honestly, they are a fairly cheap insurance policy. Get them if you like, but just remember, even if you have them on, you'll probably forget about them if you get struck at and your friends will get a show they WILL NEVER FORGET. You'd be better off being VERY CAUTIOUS, just watch out in front of you a couple steps. My father said it best "don't ever put your hands, feet, or any part of you were you haven't looked at closely"
