I made a definite choice this morning to train towards my goal, I walked 3 km in these 11.75 cm heels. By the time you adjust the steepness for my size 40, probably somewhere in the neighborhood of 11 cm, or slightly less. I can't be troubled to do the math at the moment.
I will post more about this on another thread soon, but I rarely take purposeful walks in stilettos. These are an exception, because I wanted to test the durability of heel tips on stiletto heels, and these are the shoes I designated for the purpose.
For whatever reason, these mules are super easy to walk in, but I will not tell a lie, after 3 km, I am one tired puppy. It was one of those deals where I got into the walk, and decided that I was feeling pretty good, why not go a little farther than I had planned? I don't regret it, but it definitely wore me out.
