Sandal type with long history identified by the simple outsole and normally a Y-shaped strap design. The straps are attached to the outsole where the foot is secured with the strap between a toe. Flip Flops have an open, simple design without laces, buckles or velcro with only a strap as a toe post.
The first recorded encounter of flip-flops originates from 4000 B.C as part of wall paintings.
The oldest known, currently existing, pair is from 1500 B.C and is on display at the British Museum. They are made from papyrus which along with Palm leaves, were the most common materials used for making footwear in Ancient Egypt. In other regions, similar constructions were made but with the resources available locally. The African Masais used raw hides, in India sandals were normally made out of wood where the material of choice in China and Japan was rice straw. Sisal plant leaves were used as a base for sandals in South America and in Mexico yucca plant was the main raw material source.
Different regions also had different varieties of which toe the toe strap was used with. The Ancient Greeks wore it between the first and second toes. Romans had the strap between the second and third toes. Mesopotamians wore the strap between the third and fourth toe.
The flip flop as we know it became popular when US soldiers returned from World War 2 and later on also after the Korean was, bringing souvenirs from the countries they had been. They slowly got embraced by the American popular culture and with that also redesigned in new colors. They became a popular item in beachside stores due to their ease to take on and off as well as their relative comfort.
In 1962 a Brazilian company, Alpargatas S.A., started marketing a version of the flip-flop called Havaianas. by 2010 more than 150 million pairs of havaianas were produced annually.
Depending on type of flip flop the production complexity differs. Making EVA sheet based flip flops is is relatively straight forward where leather outsole molded flip flops is a more time-consuming process.
Sheet flip flops
Sheets of EVA or other suitable material is cut into the desired shape, either by hand or by cutting dies. This will be the flip flop base where holes for the strap is punched at the same time.
The straps are made from a more elastic material such as PVC or rubber. They are molded to shape. To add sturdiness to the strap ends plastic stops are fastened. The straps are normally assembled by hand by pushing the straps through the holes. Small plastic discs are preventing the strap to go back through the holes they were introduced through.
Flip Flops can also be printed with various different methods to achieve the print desired. The most common is screen print, roller print or digital print.
Other Flip Flops
Where sheet flip flops is by quantity the by far biggest production more constructed flip flops are also common on the market. They are normally made by a cementing process with a big variety in the design complexity and layering.
