Neoprene is a synthetic rubber that was originally a DuPont proprietary name but has since become a generic term for the material. It is polymerized from chloroprene, which can be either solid or liquid. It is a favorite material for mud boots by many companies because it is stable and waterproof, and neoprene itself is not considered toxic.
Sometimes you don't realize you should be wearing your neoprene boots until you're stuck in ankle-deep mud after heavy rain or melting snow. This number doubled for areas around gates or where animals congregated for food. Having some of the best neoprene boots can be your lifesaver on those mornings.
I've seen a lot of these boots over the years. They're comfortable, waterproof, and warm, and I wouldn't think twice about even the freshest horse apples. Boots that are durable and really protect our feet and calves, no imitations allowed.
