EUC Piferi Merlin 100mm Boot - Red Metallic, size 37

Bought off the Real Real hoping to use for one of my wedding events. Sadly they run small and I can't fit in them. They have a narrow shaft around the ankle. Amazingly stylish and so sad they won't work for me. Listed as an Italian size 37. They fit closest to a US 6 in my opinion. Very small mark on the back of one of the heels and some generalized residue that is likely easily cleaned, I just haven't tried at all. Otherwise great condition! Original retail price is $775.
