Brace yourselves: 2020 is the year of the “ugly” shoe. Sure, there have been specific styles that simply won’t quit (chunky sneakers, we’re looking directly at you), but looking at the biggest shoe trends to hit this year—from clunky camping-style sandals to sneaker boots—it seems as though we’ve reached the peak of the craze. And now that the weather is beginning to take its turn toward warmer days, it’s time to hone in on one particular shoe that’s left a room divided: the Birkenstock.

Many brands have reimagined Birkenstock’s iconic Arizona sandal for a fashion-forward take on the podiatrist-approved shoe, and some, like Valentino and Rick Owens, have even collaborated with the brand for a high-fashion spin. But let’s be real: Nothing comes quite as close to the one that started it all—just ask fashion’s favorite It girls.

From Gigi Hadid and Kendall Jenner to the Olsen twins (yes, you read that right)—along with the chicest style setters—Birkenstocks have become one of the most beloved pairs of “ugly” sandals in the closets of fashion lovers everywhere.
