I saw this too and was quite suprised. Although I haven't seen the nude mad mary IRL, I just don't think that it would work IMO. I love CL nude shoes but I think they are best left to the classic styles, ie Very Prive, Yoyo, etc.
I agree with Foxy that the best color combo for the mad mary is the beige patent w/ gold studs. But I would love to see this shoe modeled on someone, I always seem to change my mind about CL shoes that I don't originally like and when I actually see them on somoeone, they look so much better.
