I have a size 10 WIDE foot. Even size "wide" shoes at the store are too snug on my feet. I have yet to find the perfect pair of flats for that reason...UNTIL I FOUND THESE! These fit perfectly (in size 11). They are roomy and my only complaint I have is if your feet sweat easily, they have  "squishy" feeling when you walk, if you're not wearing socks. Otherwise, they're great! They look kind of cool, too!
