Celine's Phoebe Philo is partially responsible for the revival, thanks to the fur-trimmed versions she designed for the French fashion brand's S/S 13 collection, but we've also noticed a smattering of celebs (like Ashley Olsen) and street muses wearing the original, old-school sandals too. Ironic (their wide, clunky design feels practically analog), understated (there's something appealing about their minimalist design), and decidedly relaxed (nothing says "laid-back" like a slip-on), Birkenstocks are above all practical, a concept we can certainly get behind during this long, hot summer.
