Our time tested Bison Classic is now available in full grain Bison leather uppers and lowers. The durability of Bison leather is legendary and responds beautifully to conditioning, giving your boots a rich patina over time that will make them distinctly “yours”. Bison have widely spaced subdermal collagen fibers that provide strength and flexibility not found in other leather. Bison leather retains 16-18 percent more natural oils then cowhide does in the tanning process. Just like our original Classic, the Bison Classic features true moccasin construction, hand locked stitching and an antique solid brass roller buckle with an adjustable ankle strap.
