Havaianas is a Brazilian brand of flip-flop sandals created in 1962. The name 'Havaianas 'is derived from the feminine form of the Portuguese word for "Hawaiians", and the pattern on the soles of the sandals is designed to resemble the straw soles of zori. Because of their simplicity and low price, the sandals - or jandals as we call them in New Zealand - became popular with Brazil's lowest social classes.
