The information on this web site reflects the personal experience of many runners, including Rick Lewis, the web site maintainer. As with any exercise program, be sure to consult your health care practioner before and during exercise, particularly if any pain or recurring symptoms persist. A foot that pronates hits the outside heel and rolls inward. A foot that rolls outward supinates. If the foot doesn't roll in enough it underpronates.
Most people pronate.
People who over-pronate a little need stability shoes. If you overpronate severely you need a motion control shoe. If you are neutral you can use mild stability or cushion shoes. If you underpronate or supinate you want a cushion shoe with no stability. Try a pure cushion shoe and supplement it with a cushion mid sole.
