If you wear Birkenstocks every day, go ahead and splurge on a designer pair that's timeless and cool. These Birkenstock x Proenza Schouler Arizona Dual Strap Sandals ($420) are impossible to find, but we did the hard work and found them still in stock. Stephanie Nguyen, our senior editor of branded content, says, "I personally love a good dad-style moment, so it was only time before I invested in a pair of Birkenstocks. As soon as I saw the brand's collaboration with Proenza Schouler in 2020, I knew those were the pair for me. Between the contrast white stitching and the velcro straps, these sandals represent my minimal style vibe to a T. Two years later, they're still my No. 1 faves!"
