Before my times here on hhplace I never even measured my heels. Still I got in contact with the "heel height in standard size", because all manufacturers claim a certain heel height which doesn't seem to change with the shoe size. It's very prominent on some Louboutin models where it's even a part of the name (like Pigalle 120 or Hot Chick 130).
Then after our discussions here I started measuring some of my heels (size 37) and found out they're a little bit below of what the manufacturer claims.
So over all the years I didn't even know my personal heel height but got a good feeling for the "heel height in standard size" 😀
What does TH stand for?
In my mind I also always subtract the platform height. Sure, a huge platform can make it more difficult to walk on uneven ground but for the steepness it's irrelevant.
