Havaianas are truly, the best rubber sandals in the world! This highly guarded recipe makes the sandals soft as marshmallows and light weighted. The addictive nature of these flip flops is largely due to an old secret rubber formula, which makes them butter-soft, bouncy, flexible and durable. There are many knock-offs of ICY COUTURE Signature Flats in the market place, but Havaianas customers know that there is no substitute for the authentic comfort and quality that only Havaianas by ICY COUTURE can provide.
