In the beginning the Bogs Ultra Mid Boot were designed to keep dairy farmers sure-footed and safe on the constantly wet and mucky concrete floors in and out of a dairy barn and to also provide these hard working dairy men with some comfort for their work weary feet. The Ultra Mid Boot by Bogs has easy on pull handles, exceptionally durable hand lasted rubber over 7mm waterproof neo-tech insulation, internal midsole with a rubber sponge for added cushion and warmth and aegis antimicrobial odor protection insole. These fantastic waterproof boots have a comfort rating based on temperature to 40degF. We may never know how these waterproof boots went from the dairy farm to the urban farm but we are glad they did.
