Medical (Symptom) Definition: Inflammation, aching, or tenderness of the tendons that attach to the inside of the front of the lower legs from the ankle to the knee.

Physiological (Cause) Definition:

Shin splints are a repetitive strain injury involving lower leg muscles and tendons and the point where they attach to lower leg bones. It is characterized by tight tibialis posterior, gastrocnemius or soleus muscles/tendons and typically weak tibialis anterior, extensor hallucis or digitorum longus muscles/tendons.

Foot Trainer Exercises address the cause by correctly relaxing tight posterior lower leg muscles/tendons and strengthening weak anterior lower leg muscles/tendons.
