COS square toe sculpted geometric heels in dark reddish brown oxblood size 37

COS heels in a dark reddish brown oxblood color. Heel height 3.5 inches. Square toe. Marked size 6 on the sticker and 37 on the underside. I’m a true 6.5 or 37 and they fit perfectly. Bought them because such a cool heel design, but I’ve never worn them out the house.
