Our nappa shoes are made from a soft, Italian nappa and flexible leather soles. Nappa leather is permeable, so avoid exposure to water and rain. To maintain the sheen and finish over time, you can use a quality leather lotion.

"I then walked over 15k steps through airports and DC and didn’t have the slightest rub. Like walking on stylish air."

Emily R.

A very stylish combination of two bestselling flats

The Crosby Slingback in Saddle Nappa
The Crosby Slingback in Ecru, Saddle and Black Nappa

We pulled from The Pointe and The Mary Jane to create an in-between style (and named it after one of our favorite downtown streets). With the polish inherent in both but a slingback silhouette that immediately marks it as breezier and ready for warm weather, it's a style meant for work and weekend.
