Please note: These were custom built for their owner. Build number E-512 B toe and heal code A-5L. I reached out to the manufacturer seeking confirmation on shoe size, but they were unable to locate exact size (they are not listed in the boot). Info they did provide was that this boot was built in June/July of 1991. I consulted with a cobbler as to the likely size, and size 5.5 Narrow was the best estimate. Again, these are estimates. It is in beautiful shape with supple leather and plenty of tread on the base. The heal has a little more wear (see photos) There is also a little leather on the inner left heel that needs re-stitched or glued. This is a beautiful pair of Tres Outlaws, lizard skin falconhead boots. And a gem for any boot enthusiast.
