In 1962, a new brand of footwear launched that would become one of Brazil’s most successful and best-known exports: Havaianas. As the country’s footwear industry started to expand, one company wanted to make something that was comfortable, inexpensive, and ideal for South America's long hot summers.

Havaianas soon became the favourite of the working class because of their affordability. Fast forward almost forty years and they featured on catwalks in Paris and Oscar goody bags in Hollywood, a surprisingly journey from their modest beginnings as the choice of farmers, builders, and tyre fitters.

Johnny I’Anson has been speaking to former employee and author Sergio Sanchez about the birth of a humble flip-flop, and how they became a global success story selling 250 million pairs a year.
