America’s hardest working boot is also America’s most comfortable work boot. Features full-grain SPR leather, steel shank, durable/resolable Goodyear Welt™ construction, covered cushion insole, and a dual-density oil- and slip-resistant polyurethane wedge outsole. Made with outstanding SPR leather, which is tanned by three separate processes for extra strength and resistance. It's been proven in test to be three times stronger, more abrasive-resistant, and more acid- and chemical-resistant than conventional tanned leather. Color: Barracuda.
