Fez — Flip-flops are among the world’s simplest shoes, but their history stretches across continents, climates, and social classes.
The basic idea is ancient: a flat sole held to the foot by a thong between the toes. Versions of this design appeared in ancient Egypt, where sandals were made from materials such as papyrus, palm leaves, and leather.
The Metropolitan Museum of Art describes ancient Egyptian sandals fashioned from papyrus, palm leaf, and halfa grass, while Johns Hopkins University’s Sheridan Libraries traces Egyptian thong sandals back thousands of years.
Early thong sandals were not limited to Egypt. Similar forms appeared across Africa, Asia, Europe, and the Americas, often shaped by local materials. Rawhide, wood, straw, and plant fibers all served the same purpose: protecting the sole while keeping the foot cool in hot climates.
From zōri to modern flip-flops
The closest ancestor of the modern flip-flop is often linked to Japan’s zōri, a flat thonged sandal traditionally made from rice straw, cloth, leather, or later synthetic materials. The design was practical in Japanese daily life because it could be slipped on and off easily, an important feature in a culture where shoes are removed indoors.
After World War II, returning soldiers helped introduce Japanese-style thonged sandals to Western markets. The design was cheap, light, and easy to produce, making it ideal for mass manufacturing at a time when rubber and plastic footwear were expanding.
The name “flip-flop” came later, reflecting the sound the sandals make while walking. In other countries, the same shoe carries different names: “thongs” in Australia, “chanclas” in parts of the Spanish-speaking world, and countless local terms elsewhere.
Rubber turns a basic sandal into a global product
The 20th century transformed the flip-flop from traditional footwear into a global consumer item. Rubber and foam made the sandal cheaper, softer, waterproof, and colorful.
Brazil played a major role in that shift. Havaianas, one of the world’s best-known flip-flop brands, launched in 1962 and says its original rubber design was inspired by Japanese zōri. The company explains that it replaced woven straw with rubber and added a rice-grain sole texture, a detail that still references the Japanese model.
From there, flip-flops spread through beaches, public pools, dormitories, street markets, and summer wardrobes. Their appeal was universal because they were affordable, easy to clean, and suited to warm weather.
A shoe between comfort and fashion
For decades, flip-flops sat at the edge of fashion: too casual for formal settings, but too practical to disappear. Designers later turned them into luxury objects, while mass-market brands kept them as everyday basics.
That contradiction is part of their endurance. Flip-flops can be a beach shoe, a household slipper, a streetwear item, or a runway accessory. They belong to both low-cost markets and high-fashion collaborations.
Their history shows how a very old design can survive by changing materials, meanings, and markets. What began as a practical solution for walking on hot ground became one of the most recognizable footwear in the world.
