When you think of Birkenstocks, you likely think of these classic Birkenstock Arizona Oiled Leather Sandals ($145). They're beloved by assistant editor Haley Lyndes, who says, "My go-to Birkenstock sandal that's never let me down is the Arizona Soft Footbed in Oil Nubuck Leather. Birkenstock has made this sandal in various versions over the years, but nevertheless, I've loved them all. Once you break it in, it's the most comfortable shoe you'll own, and its leather straps age beautifully. These sandals match so many outfits and have lasted me multiple seasons (wearing them nearly every day). They're a great walking shoe, beach shoe, boat shoe, and overall summer companion. Trust me, they won't let you down."
