Tan Calvin Klein Vivian Suede Strappy Sandle Size

Never been worn platform sandal style with a round open toe Features ankle strap with adjustable buckle closure, lightly cushioned insole Wrapped platform and heel 1/2 inch platform, 4 1/2 inch heel Smooth dress outsole. They have been in a box for a year and parts of the straps look darker than the rest; not sure why. These are a size 5 but I’m 5.5 and they fit well. I can't seem to be able to wear such high heels anymore, I guess I'm getting old.
