With an upper comprised of light brown oil-tanned leather with a retro moc toe, these work boots boast legendary Carhartt durability and look superb in the process. Supplementing this tough construction is a Goodyear welt, which means that the outsoles are directly stitched to the upper rather than glued, helping to extend the overall life of the boot by allowing for multiple repairs and replacements. Oil tanned leather upper. FastDry moisture-wicking lining. Storm Defender waterproof breathable membrane. Electrical hazard rated. Dual-density Carhartt rubber wedge flat sole.
