I would like some to hear comments regarding where the highest point of the arch (HPA) exists relative to the heel and forefoot. I take it that it would be where the navicular tuberosity lies, but this may not be the case; does anyone know this? Now I realize that there is an infinite variation of the actual height of the arch at HPA, but where is this?

If you were to draw a line from the medial 1st met head to the medial heel on a footprint (say a Harris mat), where (approximately) would be the HPA? I have had no success in finding biomechanical literature on this subject. Is there some formula one might adapt from autopsy findings?
