The Ergo-Fit steel toe on the Georgia Boot Men's Core 37 Steel Toe 8" Waterproof Work Boots allows for a better range of motion by matching the shape of your foot, without compromising the protection required by ASTM F2413 for protective toe footwear. A steel shank adds support, and the Carbo-Tec rubber outsole resists heat, chemical, abrasion, and slips.
