Well, if you have $20,000 to burn, you can get your own exquisite glass slippers. It's also possible to buy only one if you prefer. Not sure if they are actually wearable. I wouldn't risk it--just thinking of the possible pain involved if one where to break makes me cringe. Besides, one's toes would look quite crunched, good pedicure or no. Stilettos aren't really slippers, of course, but they are what most fashionistas imagine as such.
But they are lovely to look at.
Found via Cool Hunting. Which is much easier to navigate and enjoy than the horribly designed Maison Martin Margiela website. (I'm married to a web designer. I can say these things with impunity. Art should never overpower functionality where commerce is concerned.)
