I'm going to talk a bit about "maths and fit" in this first section, but if you're looking for the tutorial on how to put in your afterthought heel then just slide down to the bottom. Afterthought heel fit I played about with the maths a bit to see why they don't work for me. My heel diagonal is about 30cm [11 7/8"].
