First of all, let me make it plain that I realize that I am such an unrecontructed, unapologetic, dyed in the wool anti-high heel extremist that have no business posting in this thread whatsoever, as the Original poster has courteously made plain that she does not wish to hear "don't wear them."
However, my fingers are in one of those ornery and unstoppable moods today, and they feel duty-bound to address anyone who might need to hear it.
Listen to your body. Pain exists for a reason, and that reason is to tell us that something is WRONG. Wearing shoes that hurt your feet can not only cause you to spend a lot of time in pain, they can actually damage your feet, and even your back.
I would have been just as annoying had I lived in 18th century China.
