Havaianas are truly, the best rubber sandals in the world. They are designed and manufactured by Sao Paulo Alpargatas S.A. The ultra-high quality of Havaianas is due to a top-secret rubber recipe created exclusively by Alpargatas. This highly guarded recipe makes the sandals soft as marshmallows, light, and highly durable. There are many knock-offs in the market place, but Havaianas customers know that there is no substitute for the authentic comfort and quality that only Brazil’s Havaianas can provide.
