As someone who is a longtime leggings-plus-Birkenstocks wearer to and from pilates classes whenever the weather is warm enough to allow it, keeping up on the buzzy sandal styles the brand makes is always on my spring to-do list. The latest style I’m laser-focused on isn’t a brand-new one, but it is one that’s very relevant right now, given the continued popularity of the flip-flops trend. The style is the Birkenstock Gizeh Sandals, which Riley Keough was just spotted wearing with leggings while out and about in Los Angeles.

The Birkenstocks in question are in the style of a thong sandal, and feature the brand’s signature buckle and contoured footbed. As is the case with most Birkenstock styles, they come in a variety of materials and colors, including nubuck suede, oiled leather, riveted, and lightweight EVA. To complement her black leggings, Keough opted for a classic light tan nubuck pair. I’ll always be loyal to my Birkenstock Arizona sandals, but a pair of Birkenstock flip-flops definitely deserves a place in my collection, so on the shopping list they go.
