Prada strappy suede stiletto heels 40

Practically new- worn once inside my home. Black Nero dress heel. Size 40. Comes with Prada box, satin pink duster bag, extra set of heel tips, Prada card, and Prada embossed tissue paper. Prada Milano. Buckle embellishment. Saks wrote size 10 on the box, but I believe a size 40 is a 9.5.
