This Georgia Farm & Ranch work boot has been built with SPR leather. It's able to resist abrasions 2.5 times better and it also has 3 times the strength of traditional leathers. Plus, SPR leather is resistant to barnyard acids and caustic chemicals. The rest of the upper contains an internal padded collar, a nylon pull loop on the back (helps get these boots off easily) and a brush guard kiltie that prevents debris from getting down into these boots. A genuine leather welt enhances the footwear's durability and strength. Inside is a cushioned insole; it makes standing on your feet for long periods of time a much more comfortable experience. This men's boot also has flex-notched quarters that allow you to crouch down and bend with ease. A steel shank provides steady footing and arch support. The polyurethane X-10 outsole provides cushioning and flexibility; it's non-marking so it won't leave scuff marks onthe floors; and it has a high resistance to chemicals and oils, so it holds up nicely when exposed to those substances. Its hardy exterior, comfort features and stability make this Georgia Farm & Ranch Lacer and excellent work boot.
