It’s confirmed: This summer shoe trend, favored by the Olsen twins, is being embraced by all fashion enthusiasts.

      From the shores of Sydney to the salons of Paris, it's clear that the timelessly simple flip-flops have emerged as one of the most sought-after summer footwear trends. With their particularly sleek design, effortless comfort, and sophisticated slip-on style, these understated shoes have quickly been embraced by the upper echelons of the fashion world. Indeed, from high-end brands to the celebrity style crowd, flip-flops have evolved from being a casual, throw-on shoe to a revered accessory that enhances any chic urban or casual ensemble.

      Now, having generated interest last summer, red-and-black flip-flops have firmly established themselves as the go-to sandals for the season, with the most stylish individuals in London, New York, and even Copenhagen kicking off the sun-drenched months by continuously sporting this bold style. Naturally, it would be impossible to discuss the red-and-black flip-flop trend without referencing its origins: a trendy pair of two-toned sandals from The Row. Designed by Mary-Kate and Ashley Olsen for their Spring 2025 collection, the Dune flip-flops quickly attracted intense attention for their streamlined silhouette, controversial price, and desirability. Within weeks of their release, discussions arose regarding the ethics of investing in grosgrain ribbon and rubber sandals priced at £670, as well as the innovative idea of elevating something so commonplace to the height of luxury. And, as with anything the Olsen Twins touch, the rest of us follow suit.

      Unsurprisingly, those involved in fashion were keen to find similar styles. A jelly version from Ancient Greek Sandals, named Saionara, became a prime alternative. With a more budget-friendly price tag (£130) and a tactile finish, these sweet sandals add a youthful flair to outfits featuring breezy linens, light minis, or tailored denim shorts. Given the trend's popularity, it’s no shock that red-and-black flip-flops have made a strong comeback. From the vibrant version of Reformation’s favored Jessie sandals to the Dries Van Noten design reminiscent of beautiful Moroccan tile, discover the most stylish red-and-black flip-flops below.
