Most foot injuries can be prevented. Abnormal body structure and repeated stress are the most common causes of overuse injuries of the foot. They may not cause problems during normal activity. However, with more intense activity like jogging, overuse injuries may occur. Abnormal body structure problems include flat feet, high arches, other body problems, and poor footwear.
Some people have naturally flat feet or feet that turn in when they run.
These people tend to walk and run on the insides of their feet. Doing this too much may cause overuse injuries such as stress fractures and tendonitis. It also makes the legs rotate inward. This can cause bursitis in the hip and kneecap pain. Shoe inserts do not help hammertoes.
