Elegant shoes

Shoes worn once for a 2-hour event. Practically new, with all original packaging - box, bag, and receipt. Heel height is 10.8cm. They look very sexy on the foot. Color - dark gray. On the box and websites, the shade is called "chocolite," but in reality, they are dark gray with a slight brownish tint. Size 40. I usually wear size 39, but these shoes required size 40.
