It’s no secret that celebrities love Birkenstock shoes. Everyone from Chrissy Teigen to Gigi Hadid has worn classic sandals for years and usually opted for the iconic double buckle style. But it’s about time another couple got a nod too.

And now is a great time to try a new pair of shoes for size, as Birkenstock Madrid sandals retail for $56 but only for one day.
