More plastic shoes from Melissa

By now I own two pairs of Melissa + Vivienne Westwood Lady Dragon pumps. You know, the plastic shoes (which the boyfriend seems to consider almost the wackiest idea I ever had). I'm not keen on every pair of Melissa shoes, but I did always like their ballet flats. Especially the ones with the tiny peep toe hole and the bow on top. But never enough to buy.

These however. These I would like to spend my money on. They kind of remind me of Louboutin's Very wedge, but in plastic and with an interesting detail in the back. I can imagine these being very comfortable and appropriate for a lot of occasions. I like the fact that people always need to take in a second 'scan' of your shoes. It's like: oh, nice shoes. And second: oh, that's not very shiny patent leather, it's plastic!
I totally prefer these black and white wedges over the nude and red version, but that's just personal taste. How do you feel about plastic shoes? Would you pay $139 for these? Go visit this girl's blog to get a 20% off discount code (upper right hand corner) for the Tobi website.
