Mark this day on your calendar as historic because Christian Louboutin has come out with shoes without a five-inch heel. OK, to be fair I have seen flats. But these Christian Louboutin Miss Grey Slingbacks ($875) are identical to the knotted Loubs we've seen, only they have a 3.5-inch heel. I'm so used to seeing super-tall Loubs that this version looks stout. Yes, these would be more comfortable to trot in, but part of Loub's appeal is the high, high heel. Are you with me?
