The Copper Rough Tough Moc Boot from Red Wing Heritage sports the same design and craftsmanship that's made it a classic for nearly 100 years. Oil tanned leather from S. B. Foot Tanning Co. is naturally resistant to just about everything, making these boots durable and reliable, day in and day out. Leather insoles and cork midsoles offer comfort and support that only gets better as time goes on. The Traction Tred Cushion Crepe rubber soles provide excellent traction in variable conditions, and Goodyear welt construction ensures that those same soles won't come off prematurely.
