Your feet are not only your foundation, but your shock absorbers. The average person takes over 1700 steps a day, every day, every year. If there was something wrong with your feet (for up to 80% of us, this is the case, even WITHOUT foot pain or symtoms) the affect on your body would be like driving around town in a 1972 Ford with no shocks.
Do your shoes wear uneven or wear out faster than they should? Are you "hard on shoes?" Your shoes have holes in them? Do you have foot, ankle, leg, knee, hip, or back pain? Neck, shoulder or neck pain? Well, then see: http://footlevelers.com/human_body/foundation.php
