Oil-tanned leather is made with minimal finishing materials, which creates a distinctive natural look and feel. Oil-Tanned leather is exceptionally durable and has been used to build countless Red Wing styles over the years. It is water, stain, and perspiration resistant. Actively maintaining leather is the most effective way to ensure integrity and longevity. Learn more with our Red Wing care guides. The Work Chukka is inspired by Red Wing boots that were made for indoor work. A close cousin to the Postman line, the Work Chukka is a fan favorite for its exceptional comfort. A flexible Atlas Tred Polyurethane outsole makes the boot well-suited for bending and kneeling. The Work Chukka is built on a resoleable Goodyear welt with durable Puritan triple-stitch construction and brass eyelets. Roughout and Nubuck leather is created using a reverse-suede technique. Many tanneries split and thin hides to create suede, but our tannery simply uses the other side of the hide. This allows us to create beautiful roughout and nubuck leather with no loss of durability. Actively maintaining leather is the most effective way to ensure integrity and longevity. Learn how to care for your Red Wing Heritage Roughout and Nubuck leather.
