This 6-eye 939 Hiker Boot has a comfort-focused padded collar for extra support, a wider fit for maximum wearability, and an oil and fat-resistant air-cushioned sole for durability. The Crazy Horse Leather is a heavy-duty material with a pre-loved look. Plus, the Doc's DNA is present with grooved edges, visible stitching, and a heel-loop. The unit is secured with the iconic and reliable Goodyear welt. Crazy Horse Leather is a natural oil-finished hide, giving the boot a vintage, distressed appearance.
