Platform pump high heels shoes

Bought in Europe several years ago for approx. $160 (hot-heels.ch, model Carmen), but only worn ONCE, a couple of hours, indoors, and stored since then. Now, the patent leather is cracking a little bit on the front, and the glue has "dried out" in some places: See pics. But they are still in good condition, looking like NEW at first sight ! US size 9, a bit tight on the toes because of the shape, should also fit a 8.5. 4'' heels.
