What is the difference between over-pronation, under-pronation, and supination?
As mentioned above, some pronation is a good thing. However, some people pronate too much, or over-pronate. This means that their foot rolls too much to the inside. Too much pronation can lead to injuries, so if you over-pronate you will want shoes that limit some of that inward roll. Look for “stability” shoes if you over-pronate a little. Go for “motion control” shoes if you over-pronate a lot. Under-pronation is common in people with high arches. It means that your foot doesn’t roll inward enough. Since these people don’t have much shock absorbing roll in their stride, they generally need more cushioned shoes. Supination is the outward rolling of the foot. It generally happens at the end of your stride, after heel lifts up off the ground.
