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.

Beautiful & comfortable heel!

"This heel is the perfect height, very walkable but still gives a little height. I love the gold!"

— Kelli C. (5/5)

Pretty gold sandals!

"I purchased the sandals to wear to an outdoor event on grass - note the wide heel! I wore them once so far and they were very comfortable immediately."

— Emmeline W. (5/5)

Beautiful and comfortable! The total package!

"This shoe is clearly so very well made. I knew by the layering smell of leather when I first opened the box. , to top it off, it is an extremely comfortable shoe as well. The best of both worlds! It is not cheap, but clearly you get what you pay for."

— Rebecca S. (5/5)

Very comfortable, color not quite gold

"Love that they offer wide sizes, and the leather is buttery soft. Overall this is a great shoe that can be casual or dressed up. I just wish the color were more gold instead of copper."

— Patti B. (4/5)

Love them!

"I love these. Super comfortable. When I ordered based on the pics I thought they were more of an off white but they are most certainly sky blue. So be prepared for the color being more blue than the pics."

— Kristina B. (5/5)

Love these shoes!!

"These are beautiful and comfortable!!"

— Diana R. (5/5)

Comfy, stylish shoes

"These heels are super cute. A unique grey, leaning neutral to slightly blue depending on the lighting. I’ve worn them to multiple events without any foot pain. They seem well made. They do run narrow. I normally get a regular width and I did have to get a wide width for these. If you have actual wide feet these will not work for you."
