This is the left boot from a pair of man's brown leather cowboy boots with "fancy-stitching" in the shaft, and a medallion stitched on the foot. They have a "box toe" (although it is not square), and they have pull-straps.
Stamped in red ink inside the back part of the shaft: "7221 | 209 | 9D | MADE IN U.S.A. | INSOLE FORTIFIED FIBRE".
