They include stress fractures, tendonitis, and bone and heel spurs. Other problems include blisters, bunions, corns, calluses, athlete's foot, Morton's neuroma, and black and ingrown toe nails. Most jogging foot injuries can be prevented when actions are taken to avoid injuries. Poor biomechanics are the most common cause of overuse injuries of the foot. They may not cause problems during normal activity, but may occur with more intense activity like jogging.
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. This is called pronation. Pronating 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.
