Thank you for viewing. This is a Birkenstock mountain boot, HANCOCK. It's a heavy-duty genuine leather boot. I purchased it a few years ago at a local BIG AMERICAN SHOP and wore it for six months. After that, I applied leather care oil and stored it. Originally, it was a lighter brown than in the photos, but it has become darker due to the oil maintenance. No pets, no smokers. Please understand that this is a used item before purchasing.
