Author Description

The average American takes about 15,000 steps in a day, covering some four and a half miles. To move your body around that distance, you need a firm, flexible, and durable foundation. This is provided by your two feet, which support your entire body weight when you stand, walk, or run, and also act as shock absorbers. Noted science writers Alvin and Virginia Silverstein tell in fascinating detail the inside and outside story of the foot -- its construction of bone, muscles, nerves, skin, and nails, and the complex system that moves it. You ll also learn about the care of the foot, the injuries it can suffer, and its role in sports and exercise. Juvenile audience.
