What is pronation?
One of the most common causes of foot and leg discomfort is a condition known as excessive pronation. Normal pronation, or “turning inwards”, of the foot is necessary as the foot adapts to the ground.
With excessive pronation, however, the arch flattens then collapses, and soft tissue stretches. This causes the joint surfaces to function at unnatural angles to each other. When this happens, joints that should have been stable now become very loose and flexible.
At first, excessive pronation may cause foot fatigue. As the problem gets worse, strain on the muscles, tendons, and ligaments of the foot and lower leg can cause permanent problems and deformities.
Common signs of excess pronation:
1. When standing, your heels lean inwards.
2. When standing, one or both of your knee caps turn inwards.
3. The bottom of your foot aches or you develop bunions.
4. You develop knee pain when you are active or involved in athletics. The knee pain slowly goes away when you rest.
5. You abnormally wear out the soles and heels of your shoes very quickly.
