Foot Facts

In 1977, a 13-year-old boy had a tooth growing out of his left foot.

Women have about four times as many foot problems as men; lifelong patterns of wearing high heels often are the culprit.

There are times when you're walking that the pressure on your feet exceeds your body weight, and when you're running, it can be three or four times your weight.

Ingrown toenails can be hereditary, as genetic factors like nail curvature, nail thickness, and foot shape can increase an individual's predisposition to developing them.
