If you mean the designer shoes, they were probably donated to him and the Vatican is surrounded by Italy, where the best shoes in the world are made. If it hadn't been Prada, it could have as easily been Ferragamo, Gucci or Bruno Magli. If you mean the red color of the shoes, that is a papal tradition. Papal red symbolizes martyrdom.
No, I'm not complaining about the color. There was an article early in his pontificate about his being a little bit of a clothes horse and specifying certain mfrs and styles. It didn't mention where the money came from.
Yeah, I know about Italian shoes. I don't know WHY I know about them, but I do ... And I also get the color thing.
