BCBGENERATION LASER CUT OPEN TOE HEELS WOMEN'S TAN BROWN SHOES SIZE 7.5?

BCBGENERATION LASER CUT OPEN TOE HEELS WOMEN'S TAN BROWN SHOES Size 7.5? There size is no where to be found on these shoes. I'm a size 6 and had about a finger width behind my heel. When I measure from the tip of the shoe up to the back it's about 9 3/4 inches. If you know the size please tell me, because I can't figure it out! I believe these are leather but cannot confirm for sure. Overall good condition with some wear. Please see pictures for details. Feel free to ask any questions or request more photos.
