You know when we walk in the sand on the beach? Well, that?s how nature meant us to walk! You will notice how the sand forms a complete support under the foot. Unfortunately, instead of soft natural surfaces, we walk mainly on hard surfaces like pavements and floors. These hard surfaces cause the foot to roll inwards and the arches to flatten to gain ground contact. This condition is called ?over-pronation? and it affects an estimated 70% of the population. Over-pronation can lead to various foot problems such as heel pain and ball of foot pain. Because our feet are the foundation of our body, poorly aligned feet may also cause problems in other parts of the body, resulting in shin pain, aching legs, knee pain, even lower back pain.
There has been some speculation as to whether arch height has an effect on pronation. After conducting a study at the Rose-Hulman Institute of Technology, Maggie Boozer suggests that people with higher arches tend to pronate to a greater degree. However, the generally accepted view by professionals is that the most pronation is present in those with lower arch heights. To complicate matters, one study done by Hylton Menz at the University of Western Sydney-Macarthur suggests that the methods for measuring arch height and determining whether someone is ?flat-footed? or ?high-arched? are unreliable. He says, ?For this reason, studies investigating the relationship between static arch height motion of the rearfoot have consistently found that such a classification system is a poor predictor of dynamic rearfoot function.
Overpronation can lead to injuries and pain in the foot, ankle, knee, or hip. Overpronation puts extra stress on all the bones in the feet. The repeated stress on the knees, shins, thighs, and pelvis puts additional stress on the muscles, tendons, and ligaments of the lower leg. This can put the knee, hip, and back out of alignment, and it can become very painful.
When you overpronate your foot rolls inwards causing the lower leg to rotate inwards too. It's thought that this increases stress on the soft tissues of the lower leg causing pain and inflammation, or more commonly known as shin splints.

Side Step with Opposite Reach. This exercise is designed to load the "bungee cord system" of the gluteal muscle and its opposite, latissimus dorsi muscle to keep the foot from overpronating. Because the opposite arm swings across the front leg when walking, this exercise creates tension in the muscles all the way from the front foot, across the back of the hips and back, to the fingers of the opposite hand. Movement Directions. Stand with left foot on top of the dome of the BT. (Note: For added balance, the right foot can tap on the ground, if needed). Reach right leg out to the side of the BT, and tap the ground while squatting down on the left side and reaching right arm across the left knee. Push down with left big toe while squatting. This activates the arch of the left foot and strengthens all the stabilizing muscles on the left side of the lower body. Return to starting position. Perform 8 to 10 repetitions on each leg.
Massage and stretch the calves to increase dorsiflexion at the foot/ankle. Dorsiflexion is the bending at the ankle. By improving the dorsiflexion, one will have more flexibility at the ankle, which will allow the foot to over-pronate less. Massage the IT Band with a foam roller or tennis ball to quiet down the tightness throughout this part of the leg. The IT Band attaches from the glute maximus and runs down the side of the leg into the knee area. When the IT Band is tight it will accelerate the force of the leg moving inward, which will cause the foot to move inward as well. It is often that tightness through the IT Band that promotes over-pronation. Decreasing over-pronation, which is very prominent in runners, will help add endurance, speed and efficiency to your run and ultimately place less stress on your body.
