Vintage Shoe Company Issac Tanker Boot. I've becoming increasingly interested in boots lately. I think it's the bundled-up, worn-in look that consistently pulls me. This Tanker boot utilizes straps instead of laces. Used as a Military boot in the 1940's, the straps allowed for security and ease moving about the fields and tanks during battle. Domestically-made, this is another investment that will last you a lifetime.
