Georgia Boot® Carbo-Tec™ Farm and Ranch pull-on boots have leather that's superior to the others on the market.The upper is hard-wearing SPR™ leather, a great material for dirty jobs because it's ready to take on caustic chemicals and common barnyard acids that dry out lesser leathers. SPR™ leather also is very soft and is broken in right out of the box.Comfortable work boots are important when you work long hours. These 11-inch wellington boots have the patented Comfort Core® insole. It cushions your foot and pushes air through the insole with every step. The fiberglass shank provides arch support.The Carbo-Tec outsole is highly flexible so you can move with ease. It also resists chemicals, slips and oil.
