There are many reasons your feet could hurt. First, you could be wearing the wrong size shoe or a shoe that does not support your feet properly. Also, you may have switched up your activity level from the ordinary. For example, if you have begun exercising or running. You have a deeper more serious problem such as plantar fasciitis, achilles tendinitis, flat feet, ingrown toenails, neuromas, a stress facture, bunions or many other common, but serious foot problems. If you are experiencing pain, it is not normal and you should have it looked at by a podiatrist. Many common foot problems can easily be treated in their early stages, but if you wait, the problem will only get worse.
