Supination is not a natural state that is forced upon someone anatomically unless they had an improper surgical reconstruction or a highly unusual anatomical variation. Supination in the general population is a strategy that involves muscles overstabilizing against the natural pronation imposed by the subtalar joint. We use our insole system in these cases, because when the foot is supported against overpronation, the nervous system will feel less of a need to use muscles to brace the ankle into supination.
