Modeled after Red Wing's original work boot style, the 8138 is a 6-Inch Moc Toe featuring Briar Oil Slick leather, white Traction Tred rubber outsole, triple stitched quality and Goodyear welt construction. Red Wing's Classic Work boots were designed and built to withstand the daily rigors of the work day on the farm and in the factory. The lightweight crepe sole featured a minimal tread design to reduce the mud that would cling to a farmer's boots but still provide the underfoot comfort the work day required. Red Wing would brand the crepe sole as the Traction Tred sole. These classic boots featured a moc toe design. The name came from the word moccasin, the Algonquian Indian word for shoe. This combination of the u-shaped moc toe leather upper and the white crepe sole would become the iconic boot style for the Red Wing brand. It is one of the oldest Red Wing styles and a best-seller.
