The shoe known in Australia as a “thong” is one of the oldest styles of footwear in the world.

Worn with small variations across Egypt, Rome, Greece, sub-Saharan Africa, India, China, Korea, Japan and some Latin American cultures, the shoe was designed to protect the sole while keeping the top of the foot cool.

Australians have long embraced this practical but liberating shoe — but history shows we can’t really claim to it as our own.
