Many years from now, when the streets of New York are soaked with the perspiration of another record-setting heat wave, your grandkids will turn to you and ask about the great flip-flops debate of summer ’25. They will press you for details. They will suss out the consensus. They will reference pictures of Jonathan Bailey wearing flip-flops on the red carpetand pictures of European cool guys wearing flip-flops on the fashion week junket.

In turn, you will settle into your rocking chair, crank the AC higher, and direct them to this very article, where it was first brought to your attention that Havaianas—the only flip-flops you need and, probably, the only flip-flops you should buy—are on sale for $15 at Amazon, a sweet lil’ bargain on Brazil’s most notable summer export.

At that point, you’ll have to do a little explaining—about how Prime Day was actually four days that year, and about your resolve, despite the number of fancy designer flip-flops flooding the market, to stick with the brand that does ‘em best, for, again, $15 a pop. But whythose pesky grandkids will ask. Did The Row’s $700 rendition ever tempt you? Because GQ said so, you’ll say. Because Havaianas remain the preferred flip-flops of Copenhagen fashion girlies, SoCal surfer bros, and, uh, all of Brazil. Because they’re humble, unpretentious, and hugely fun to wear, like the flip-flop emoji made sentient.

Still not sure where you stand on the flip-flops debate? All we ask is that you think of your future grandkids, and how delighted they’ll be when they fish a pair of Havaianas out of your closet and speculate on what they would’ve done during the fateful summer of ’25.
