Even the gods and heroes were primarily depicted barefoot, as well as the hoplite warriors. They fought battles in bare feet and Alexander the Great conquered his vast empire with barefoot armies. The runners of Ancient Greece had also been believed to have run barefoot. The Romans, who eventually conquered the Greeks and adopted many aspects of their culture, did not adopt the Greek perception of footwear and clothing. Roman clothing was seen as a sign of power, and footwear was seen as a necessity of living in a civilized world, although the slaves and paupers usually went barefoot.

The more intricate the insignia and the higher up the boot went on the leg, the higher the rank of the soldier. There are references to shoes being worn in the Bible. In China and Japan, rice straws were used. Starting around 4 BC, the Greeks began wearing symbolic footwear. These were heavily decorated to clearly indicate the status of the wearer.
