So, I haven't seen pictures of someone actually wearing these until now. I suppose it's not all that farfetched to see them on Elin Kling, fashion journalist and blogger extraordinaire. I don't speak Swedish, but I'm assuming in her posts she's saying "Gosh damn, I can't believe I'm actually walking on nails!" and "I'm definitely in need of a foot massage now."
I still don't understand how anyone can balance on those, but I give her double kudos for wearing them in the name of fashion! I admit they do look pretty hot though.
