NWT RARE Zara metallic boots 36/6; 5.5

AMAZING rare boots by Zara from 2014. The color is a dark silvery metallic with subtle leopard spots and a 'fur' pattern. Reminds me of seal fur. Searched everywhere for these but...they're very tight fitting. I'm no stranger to torturing myself with shoes, but I'm not sure I'd be able to wear these. I'd call the size 5.5 or even 5. Come with original tags (and replacement heels). Genuine leather.
