The arch of the foot is held up by tendons that extend from the shin muscles.If the arch falls from lack of proper support, the shin muscles over work, resulting in cramping, fatigue and muscle pain.
Shin pain is often categorized as shin splints. The pain may start out as a dull ache, but will gradually become more intense.
Increased stress in the lower leg muscles around the shin occurs when the foot is not supported correctly.
If left untreated, the muscle will eventually tear.
The highlighted tendon (Tibialis Anterior Muscle) connects from the bottom of the arch to the tibia. When the arch is not supported properly and drops lower to the ground, the tendon has to work harder.
Orthotics help provide proper arch support while reducing pressure and stress on muscles of the shin.
