The shoes were created by the Belgian artist Paul Schietekat for an exhibition in 2006, and there are not thought to be any plans to release them commercially.

Oh, I stole the Posh Spice joke from one of comments to the article.
Now, I will pretend I didn't see these so keep them in mind when you want to send me a Christmas present. ;-)
