Insole charts:

It is important that you learn to listen to your body. Even though the given coordinates on the charts are the ones we recommend you to start with, you can change the location of the stud(s) by one unit horizontally or/and vertically to find out where you get the best effect. The reflection zone map here illustrates the reflection areas for different parts of the body. The given coordinates on the charts are within these areas, and you can move the place of the studs within these areas to test where you get the best effect.
