The Row Constance Leather Heeled Sandals

"They’re crafted from supple leather to a barely-there silhouette with pin-thin thong-style straps and square toes, while the lacquered sculptural kitten heel sets them apart from your average heeled sandals."

I like to have a little bit of space in my sandals and I'm a size 5.5. They fit true to size though so if you're a size 6, they'd work perfectly.
