The majority of the population have a normal to low arch. Even though the arches appear to be normal most of us suffer from over-pronation during walking, running and standing, due to the hard, flat unnatural surfaces we walk on, combined with wearing unsupportive footwear. With every step we take the arches flatten and the ankles roll inwards. Pronation itself is not wrong because we need to pronate and supinate as part of our natural gait cycle. Pronation (rolling in) acts as a shock-absorbing mechanism and supination (rolling out) helps to propel our feet forward. Over-pronation occurs when the foot pronates too deep and for too long, not allowing the foot to ‘recover’ and supinate. Over-pronation hampers our natural walking pattern. It causes an imbalance and leads to wear and tear in several parts of the body with every step we take.
Over-pronation is very prominent in people who have flexible, flat feet. The framework of the foot begins to collapse, causing the foot to flatten and adding additional stress to other parts of the foot. Therefore over-pronation can often lead to a case of Plantar Fasciitis, Heel Spurs, Metatarsalgia, Post-tib Tendonitis and/or Bunions. There are many causes of flat feet. Obesity, pregnancy or repetitive pounding on a hard surface can weaken the arch leading to over-pronation. People with flat feet often do not experience discomfort immediately, and some never suffer from any discomfort at all. However, when symptoms develop and become painful, walking becomes awkward and causes increased strain on the feet and calves.
Eventually, over-pronation can lead to a full list of maladies including flat feet, plantar fasciitis, plantar fibroma, neuromas, heel spurs, shin splints, ankle sprains, bunions, hammertoes, calluses, and pain in the arches, knee, hip and lower back. But it doesn?t have to go that far, because there are steps we can take to correct the over-pronation. In the vast majority of cases, we?ll prescribe custom foot orthotics, which will realign your ankles, redistribute the weight, support the arch and reduce the twisting. Many orthotics will fit snugly into your normal shoes. Although we?ll also take a look at the type of shoes you wear to see if they are contributing to the problem.
When sitting, an over-pronating foot appears quite normal, i.e. showing a normal arch with room under the underside of the foot. The moment you get up and put weight on your feet the situation changes: the arches lower and the ankle slightly turns inwards. When you walk or run more weight is placed on the feet compared to standing and over-pronation will become more evident. When walking barefoot on tiles or timber floors over-pronation is more visible, compared to walking on carpet or grass.
Non Surgical Treatment
Anti-Pronation Insoles provide a unique foot support system that aligns the lower body. The major cause of foot and leg pain is over pronation (rolling over of the feet) which causes excessive pressure on the muscles, ligaments and bones of the lower body. Running insoles treat the underlying cause of over pronation and prevent future occurrences of the associated foot or leg condition. A project conducted at the NIKE Sport Research Laboratory studied the effects of orthotics on rear foot movement in running. Nine well-trained runners who wore orthotics were chosen as subjects. The results of the study indicated that orthotics reduced rear foot movement by roughly one degree or approximately nine percent of the amount found in runners not using orthotics. The average reduction of the maximum velocity of pronation was fifteen percent. Thus this study indicates that orthotics and insoles control over pronation which will treat and prevent many sporting injuries.
Custom-made orthotics supports not only the arch as a whole, but also each individual bone and joint that forms the arch. It is not enough to use an over-the-counter arch support, as these generic devices will not provide the proper support to each specific structure of the arch and foot. Each pronated foot?s arch collapses differently and to different degrees. The only way to provide the support that you may need is with a custom-made device. This action of the custom-made orthotic will help to prevent heel spurs, plantar fasciitis, calluses, arch pain, and weakness of the entire foot.
