Narrow size 39 European Mackin J Clear Lucite Wedges 4 inch - these run small. I was given these as a promotional item for modeling. They came with slight discoloration on the heels (I am unsure if that’s natural). It fits an American Narrow 7.5 comfortably (my actual size is a narrow 7, and they had a bit of room) — I definitely see an American Narrow 8 fitting snuggly. I wore these magnificent Barbie / Cinderella Glass Slippers on approximately 3 shopping excursions. Being a 42-year-old mother who frequents children’s activities, these wedges are not a part of my repertoire any longer — they are too “youthful” and trendy for me! Truly, these wedges exude elegance and elicit the illusion of long, sleek legs. The heels are hard lucite; they are not incredibly comfortable but they are exceptionally chic.
