Vintage Larry Mahan Mens Size 9.5/10 Brown Leather Western Cowboy Boots 1980’s

I can’t determine the size exactly, the boots are stamped 4105, which is the width and size. They fit like a men’s 9.5 or 10. The heel to toe measurement is approximately 11.75”. I am happy to take more measurements if desired. The leather is incredibly soft and supple.
