Those shoes are really something, I must say. I'd love to try them for a day, maybe, but I don't think they'd become a staple of my wardrobe. They're art, really.
For anyone looking for an insole designed to make high heels more comfortable, maybe check out
Insolia inserts -- I haven't tried them, but they were recommended to me (by DailyCandy.com, hehe). Once I pay off this month's credit card bill, I think I'm definitely going to order a pair. I'm always looking for a solution to that killer pain in the ball of your feet, since I love heels so much!
My dream is to have a closet full of Christian Louboutins, Jimmy Choos, etc... They say expensive heels are much more comfortable. Considering how chronically uncomfortable shoes from Payless are, I'd believe it.
