So I bought these boots around three years ago and I am just now doing the review. First things first; I work in a tire factory and I step in all sorts of chemicals and oils and rubber all day long. The boot tread held up great even in these conditions. Let me also say I wear my boots all the time. Even wore them hiking a few times. Here is my biggest complaint; The ankle supports are some sort of plastic material. After just a few months of use the ankle support started breaking apart and bits of sharp plastic were sticking my ankles. I had to end up making a cut in the liner and pulling all that broke plastic out. That kind of defeats the purpose of ankle support though. Other than that as long as you keep them cleaned and shined they'll last you a long time. Plus they're made in America.
