Zara chunky black heel

Cute sandal pumps that wrap around the ankle. Never worn except inside the house when trying them on. Like most of the shoes I’m selling, these are a size 36 (which in Euro sizes tends to be a 6.5 and I am a true 6 leaning closer to 5.5). Anyway, I’ve kept them in pretty good shape. The leather lining on one of the straps is flaking off. I’ll send more pics!
