I like heels, but only for a couple of hours at a time. Life is too short to wear uncomfortable shoes. My ENFP friend acts like it's a point of pride that she doesn't own a pair of flats. Which seems like an idiotic thing to be proud of, to me.
Actually, if you're really looking to hurt someone with them, step on them.
What the quantification does not address is how much pressure a woman stumbling about in high heels would exert if she stepped on you. For that the British physics institute directs people to its web site where it records that a 100 pound woman in stilettos will exert pressure under her foot that is 20 times that of a 6,000 pound elephant.

I like to wear heels all the time. I'm not very tall and I like actually being able to reach things and see above children's heads. It's easier than carrying a stool.
There seems to be a range of heels though and I don't wear stilettos. I teach in them for several hours at a time so I tend to go for comfortable platforms for work. I'll wear shorter, thinner heels for a few hours for other occasions, they will nearly always have a broader base though and be under 4 inches since I don't like to be in pain or fall over. If the goal was increased height and grace then falling over defeats the purpose.
