Shoes Without Heels

I'm wondering what everyone thought of these Antonio Berardi shoes when they came out.  When I first saw the photos I was completely lusting after them, but how in the world do you walk in them?  I get that you stand on your tip-toes, but what if you forget that you can only stand on your tip-toes?

What if you have a margarita, feel a little relaxed and try to put your heel down?

Anyway–just wondering…..they are pretty cute.
