Tess, who has been known on more than one occasion to wear her flip-flops in December, swears by Havaianas all year long. It's not hard to find flip-flops these days--everyone from drugstores to the top designers seems to be making them--but these all-rubber thongs from Brazil stand out from the crowd (just ask Brazil native Gisele, who practically lives in her Havaianas during her downtime from modeling). The manufacturers say the top-secret recipe makes the sandals "soft as marshmallows, light, and highly durable," and our feet agree. The best part of all? They're cheap enough that you can buy a pair for every occasion.
