Sandals were the most common footwear in most early civilizations, however, a few early cultures had shoes. In Mesopotamia, (c. 1600-1200 BC) a type of soft shoes were worn by the mountain people who lived on the border of Iran. The soft shoe was made of wraparound leather, similar to a moccasin. As late as 1850, most shoes were made on absolutely straight lasts, with no difference between the right and the left shoe.
