You actually picked an odd period.
between the late 1800s and the early 1900s shoe manufacturing became industrialized.
Before 1890 you could get custom made boots from a cobbler or make your own.
They varied from very crude to very fine.
The crude versions were often made the same for both feet. Not right and left like we expect now.

By about 1910 you could order a wide selection of boots from the Sear's catalog.
