A warm-weather STAPLE for sunny days

A staple silhouette in our collection, this flat sandal is reminiscent of Audrey Hepburn in ‘Roman Holiday’ and dreamy summer getaways. We added a modern edge with the elongated, squared-off toe and slimmed down our signature “X” strap design for a flattering, barely-there look.

Overall rating: 4.707521 / 5 from 359 reviews.

Great sandals!

"I love these shoes. Fantastic quality and comfort. I can’t believe how easy it is to wear them. My feet are picky and I’m absolutely loving these sandals. I got my usual size for sandals which is one less than my usual size for sneakers. And my foot is a bit wide in front but I bought the medium and it’s just right."

— Amy M. (5/5)

The Flat Sandal

"These are hands down the most comfortable sandals I've ever owned. I loved them so much that I bought them in two colors! I recently wore them on a trip where we walked all over the city for hours each day, and they were comfortable from morning until night. No blisters, no sore feet…. just great support and style. They go with everything and have quickly become my go-to summer sandal. Highly recommend!"

— Lindsey O. (5/5)

Love my new sandals !

"I considered buying these for a long time now, and finally went for it. I’m so pleased with them! They are gorgeous and fit perfectly. I don’t think I could walk miles in them, but they held up well while walking through the airport on a recent trip, no blisters. They’re very comfortable as well. I’m sure they’ll get a lot of use out of!"

— Alicia H. (5/5)

FINALLY

"I have been searching for these sandals forever! I travel so much for work, I try to keep packing to a carryon. The sandals are the holy grail! They look great with a suit, with a sundress for dinner and even on travel days when I’m clocking 10,000+ steps. I’m 60, have had compliments from all ages, and look put together without taking up luggage space. Already dreaming of the tan pair. Chef’s kiss! 💋"

— Walter K. (5/5)

Well made sandal and has

"Well made sandal and has the minimalist style I was looking for. Very versatile. I like the flat style but it still has support and some cushion. They do run on European sizes so consider that with width. I think these run a little narrow. I am generally a 10 or 10. 5 and I got a 41. 5. which translates to a 10. 5. It's a good fit!"

— Katrina T. (5/5)

Cute and comfortable

"The minimal design is super cute. These didn't require a break-in period. Just one pinky toes got a bit chafed after walking in these for 20 minutes. I normally gravitate towards comfort and wear barefoot shoes, but needed a stylish option, and I'm glad I didn't have to compromise on comfort. In terms of sizing, I noticed that with other brands, I'm a US 7. 5/EU 38 but with these, I'm a EU37. 5."

— Minjeong K. (5/5)

"Unfortunately the sizing was off for me. I normally wear a size 6 wide but in this sandal I ordered a 6 M since sandals dont require as much room as the Demi but this was a miss. I would need a smaller size 35.5 EU and with the extra width on the toe box. Will be returning."

— Priscilla (1/5)

Not it for narrow feet

"I had high hopes for these as I loved the style. These are still too roomy for narrow low volume feet (esp near toes) . I have bought medium width shoes from other brands with a better or same loose fit. So not really narrow. And , I’m a connoisseur of true narrow size 39 shoes."

— Eugenie B. (3/5)

NAppa SandL

"Lovely sandal. I chose a size 5. 5 and the length is perfect but I would have preferred the straps over the top of the foot to be less long, in other words to fit more snug to the top of my slender foot. Color and material is gorgeous."

— Lois M. (4/5)

I LOVE THESE BEAUTIFUL SANDALS!

"Last year I bought a similar low-heeled version. I love them especially because I have a wide foot and they look so good on my foot. They are so high quality, well made, quality leather, and so comfortable."

— Ann F. (5/5)
