Pronation is the way the foot rolls inward when you walk and run. It is part of the natural movement that helps the lower leg deal with shock. Some people pronate more (overpronation) or less (underpronation) than others. Though this is not bad in itself, it does affect the way you run and it may increase the likelihood of injury. This makes your pronation pattern an important factor in choosing the right shoes.
Although there are many factors that can contribute to the development of these conditions, improper biomechanics of the body plays a large and detrimental role in the process. Of the many biomechanical elements involved, foot and ankle function perhaps contribute the most to these aches and pains.
Symptoms can manifest in many different ways. The associated conditions depend on the individual lifestyle of each patient. Here is a list of some of the conditions associated with Over Pronation. Hallux Abducto Valgus (bunions). Hallux Rigidus (stiff 1st toe). Arch Pain. Heel Pain (plantar fascitis). Metatarsalgia (ball of the foot pain). Ankle sprains. Shin Splints. Achilles Tendonitis. Osteochondrosis. Knee Pain. Corns & Calluses. Flat Feet. Hammer Toes.
Firstly, look at your feet in standing, have you got a clear arch on the inside of the foot? If there is not an arch and the innermost part of the sole touches the floor, then your feet are over-pronated. Secondly, look at your running shoes. If they are worn on the inside of the sole in particular, then pronation may be a problem for you. Thirdly, try the wet foot test. Wet your feet and walk along a section of paving and look at the footprints you leave. A normal foot will leave a print of the heel, connected to the forefoot by a strip approximately half the width of the foot on the outside of the sole. If you?re feet are pronated there may be little distinction between the rear and forefoot, shown opposite. The best way to determine if you over pronate is to visit a podiatrist or similar who can do a full gait analysis on a treadmill or using forceplates measuring exactly the forces and angles of the foot whilst running. It is not only the amount of over pronation which is important but the timing of it during the gait cycle as well that needs to be assessed.
Non Surgical Treatment
Although there is no actual cure for over-pronation it is possible to correct or at least reduce this problem. In order to restore our normal foot function an ‘orthotic’ or orthotic insole device is placed inside the shoes. Orthotics are designed to realign the foot and ankle bones to their natural position. This in turn restores our normal foot function and it helps alleviate not only foot problems but also ailments in other parts of the body i.e. the legs, knees and lower back. In addition to wearing an orthotic, it is recommended to wear supportive shoes, like good quality athletic footwear with a firm heel counter and sufficient flexibility in the forefoot area.
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.
