I've recently learned that snake-proof boots exist. I haven't bought any yet because I can't go and try them on, but they seem like an excellent idea. I've done some research into them, and I've read that they do actually work quite well- snakes can't bite too terribly hard, so can't pierce the material. There's also a sort of shin guard device you can use, that straps onto your lower legs and can work with many types of footwear. Both are meant to protect the legs from snake bites, as most snake bites that don't occur from handling the snake, happen when someone treads on one.
Depending on where you live, this may or may not be needed. I live in Texas, which means snake protection is generally a good idea. We have many snakes, including multiple venomous species. I don't intend to step on any intentionally, and I do my best to watch my step when exploring, but the boots seem like a good precaution just in case. They're effective against thorns as well, which is nice, and will probably come in use frequently.
