I finally settled on these wedges from Piperlime, (after years of looking):
They are so completely uncomfortable; I remove them after putting them on, as soon as possible (even if I still have to walk through a parking lot). I only wear them if I absolutely have to, and only if I know I will be sitting for most of the time.
I get tons of compliments. They were a great price. And I really needed a pair. We'll see how long they last - or rather, how long I last.
