Oh, flip-flops. The world’s most unfashionable shoe per many a style maven. During New York Fashion Week, however, the casual sandal appeared on several runways, from minimal versions at Michael Kors and Dion Lee to embellished takes at Marc Jacobs. Even Rihanna put out a—wait for it—heeled version at her Fenty Puma show. Styled with elegant attire from sequined gowns to satin separates, the look was totally unexpected. And after we got over the initial shock, the concept started to make sense what with the rise of nonchalant fashion. On the heels (pun intended) of the triumph of slides this past summer, designers are putting forth the next iteration of easy footwear—and to be honest, we’re kind of into it. A pared back flip-flop with a dazzling dress is the epitome of laissez-faire style—the idea that one simply can’t be bothered with a stiletto. So chic! Also, after a week of traipsing through Manhattan in heels, comfort sounds extremely appealing. Witness the trend ahead. We’ll be keeping our eye on the London, Milan and Paris runways to see if flip-flops will indeed become the It shoe of spring.
