5. Pronation
Pronation of the foot can also often lead to imbalances and pain in the knees and other joints. This happens because the line of gravity from the hip through to the foot is no longer straight. Instead of being able to push through the foot and bend the leg like a spring, the pressure will now be dislodging the patella for some serious discomfort.
The best solution is to again speak with a professional, who should be able to recommend orthotics (shoes or inserts) to correct the problem.
