Prevention

The American Podiatric Medical Association offers the following tips for preventing foot pain:

Don't ignore foot pain -- it's not normal. If the pain persists, see a doctor who specializes in podiatry.
Inspect feet regularly. Pay attention to changes in color and temperature of the feet. Look for thick or discolored nails (a sign of developing fungus), and check for cracks or cuts in the skin. Peeling or scaling on the soles of feet could indicate athlete's foot. Any growth on the foot is not considered normal.
Wash feet regularly, especially between the toes, and be sure to dry them completely.
Trim toenails straight across, but not too short. (Cutting nails in corners or on the sides increases the risk for ingrown toenails.)
Make sure shoes fit properly. Purchase new shoes later in the day when feet tend to be at their largest, and replace worn out shoes as soon as possible.
Select and wear the right shoe for specific activities (i.e., running shoes for running).
Alternate shoes. Don't wear the same pair of shoes every day.
Avoid walking barefoot, which increases the risk for injury and infection. At the beach or when wearing sandals always use sunblock on the feet, as you would on the rest of your body.
Be cautious when using home remedies for foot ailments. Self-treatment can often turn a minor problem into a major one.
It is critical that people with diabetes see a podiatric physician at least once a year for a checkup. People with diabetes, poor circulation, or heart problems should not treat their own feet, including toenails, because they are more prone to infection.

Skin Creams and Foot Baths

Skin creams can help maintain skin softness and pliability. Taking a warm footbath for 10 minutes two or three times a week will keep the feet relaxed and help prevent mild foot pain caused by fatigue. Adding 1/2 cup of Epsom salts increases circulation and adds other benefits. Taking footbaths only when feet are painful is not as helpful.

A pumice stone or loofah sponge can help get rid of dead skin.
