Zara Silver slingback flats (size 39) NWT

Brand new Zara silver metallic slingback flats...elegant for evening wear, or can be worn casually with jeans... The size states 39, which would mormally be an 8 1/2, but it runs smaller and more narrow. I'd say they'd fit a sz 7 narrow. There is no elastic in the slingback for size adjustment. Reposhing this item. It is not a proper fit. Loved it, but have to rotate for something new. Questions? Leave a comment below!
