Havaianas is a Brazilian flip-flops brand created and patented in 1962. It is currently owned by the Brazilian manufacturing company, Alpargatas SA. Inspired by Japanese zori sandals, Robert Fraser became the first to mass produce rubber flip-flops.  The name Havaianas comes from the feminine form of the Portuguese word for "Hawaiian", and the pattern on the sandal sole is designed to resemble the sole of zori straw. Initially, all Havaianas featured a white sole with a colored outsole and strap. Due to their simplicity and low price, these sandals became popular in Brazil's lowest social class.
