Causes - Shin Splints

Shin splints are caused by an overload on the shinbone and the connective tissues that attach your muscles to the bone. The overload is often caused by specific athletic activities, such as:

Running downhill

Running on a slanted or tilted surface

Running in worn-out footwear

Engaging in sports with frequent starts and stops, such as basketball and tennis

Shin splints can also be caused by training too hard, too fast or for too long.
