Some shoe trends arrive loudly. Others quietly take over your Instagram feed until suddenly every fashion person seems to be wearing them. Right now, it’s all about minimalist black flip flops with a subtle heel — and Hailey Bieber just confirmed they’re officially the sandal of the summer.

In photos posted to Instagram on May 24, the Rhode founder styled a pair of sleek black heeled flip flops with multiple looks while exploring Seoul. What made the outfit stand out wasn’t anything overly styled or complicated. In fact, it was the opposite. The barely-there sandals made relaxed basics, tailored pants, and casual tourist outfits look instantly cooler.

The appeal of this trend is how effortless it feels. These aren’t your typical beach flip flops. The updated versions have sculptural shapes, square toes, soft leather, and tiny heels that make them feel more fashion-editor favorite than poolside essential.

If you want the same look, Mango’s Wedge Leather Sandals are one of the best affordable options right now. The sleek black leather and minimal wedge silhouette look incredibly similar to the pair Hailey Bieber wore — and they somehow make even the simplest outfit feel polished.

Another bestseller fashion insiders love is the handcrafted in Brazil, Square Toe Lily Sandals by TKEES. With their square toe and minimalist design, they’re the kind of shoe that works with everything from linen trousers to slip dresses and oversized denim.

And honestly, that’s exactly why this trend is everywhere right now. These sandals don’t overpower an outfit. They quietly make it look more expensive.

You can wear them with:

• relaxed white pants and a tank top
• oversized button-down shirts
• simple black dresses
• tailored shorts
• vintage denim and a white tee

Minimal effort, maximum “fashion person on vacation” energy.
