Heel Thyself

While I have never worn high heels myself and, quite frankly, am not much of a fan of them on others (they just look painful), here is a weird idea: convertible high heels. Here's what would make this idea really cool: if they could be adjusted automatically while they are being worn. How cool would that be? You're standing there, talking up someone at a party and, suddenly there is a whirring sound, and her (or his) heels grow like four or five inches. Sort of like a sexy Nosferatu. Even I would go for that.
