Strappy Gold Cole Hahn Nike Air Sandals with heel

Gold Cole Haan sandals with 2 inch/5 cm heel. Light signs of wear: some gold finish worn off around base of shoe and on foot bed, as shown in photos. I believe that the sandals are size 6.5 (Is this is always been my standard size and Cole Haan), but I cannot find a size directly on them. Length from toe to back of shoe is 9.5 in / 24 cm. Width at widest toe is 3 3/8 inch/ 8.5 cm.
