I don't wear them either. I'd probably fall over!

Have any of you ever tried an inverted heel - where the heel is sunken down, so it's a little lower than your foot (if I'm understanding correctly).

I have an old pair of "Earth" shoes that I think had this - they've been awesome, so incredibly supportive. But they're starting to fall apart, and the last pair that I tried from them didn't seem to have the same feature.
