Rainbows are simply the best flip-flops out there. Worth every penny. I've been wearing them daily for probably 10 years and I've only gone through maybe 5-6 pairs. I've never had a strap break. Ever. The only reason I have to replace them is because I literally wear holes through them after about 18 months or so. But if the strap does somehow break before you wear clean through them, they have a lifetime warranty! What kind of flip-flop company does that? A bad-ass one, I tell you! A note to first time users: you have to break them in; they won't seem comfortable straight out of the box. But after a day or so they are literally custom-fitted to your feet and super comfortable.
