I go through a pair of snake boots about every year to every other year. I have found that leather/man made material seems to last longer and has better water resistant qualities. I just bought a pair of Danner's and this is my second pair. I expect to get at least two years out of them. I have had some luck with Rocky Pro Lite 16's but they don't stay water proof long. They are 100% man made material. A pair of Gokey's or Russell's will last you most of your life, but will leak with the best of them.
