Even though I don’t like Sex and the City, I completely understand why Carrie Bradshaw collected Manolo Blahnik shoes until she went broke. Yes. Yes. Yes! Shoes are essential and oh so useful. For example, when you have a lot of shoes, then each morning you can step into whatever color and style fit your mood.

However, when you are traveling, shoes are pretty heavy and take up heaps of space. So, for a while now, I’ve been thinking about inventing high heels with removable heels so that I could wear flats from time to time.

It seems that I’m one step behind, however. Young German designers have come out with something far crazier than I ever dreamed up. It’s called “Nat-2interchangeableduofunctionshoe.” If you’re having a hard time dividing up that monster word, let me explain it to you in plain English. Basically, you can make flip flops out of sneakers…with just a zipper. How does it work? These photos explain it far better than I can.

This crazy combination won the Innovation & Design Award 2007. I don’t wear sneakers often, but I really want to go and grab a pair of these right now!
