Pronation is the inward movement of the foot as it rolls to distribute the force of impact of the ground as you run. The foot "rolls" inward about fifteen percent, comes in complete contact with the ground, and can support your body weight without any problem. Pronation is critical to proper shock absorption, and it helps you push off evenly from the front of the foot. Although pronation is a natural movement of the foot, the size of the arch can affect its ability to roll, causing either supination (underpronation) or overpronation. If you have a normal arch, you're likely a normal pronator, meaning you'll do best in a shoe that offers moderate pronation control. People with flat feet normally overpronate, so they do well in a motion-control shoe that controls pronation. High-arched people typically underpronate, so they do best in a neutral-cushioned shoe that encourages a more natural foot motion.
Over-pronation has different causes. Obesity, pregnancy, age or repetitive pounding on a hard surface can weaken the arch leading to over-pronation. Over-pronation is also very common with athletes, especially runners and most of them nowadays use orthotics inside their shoes. Over-pronation affects millions of people and contributes to a range of common complaints including sore, aching feet, ball of foot pain, heel Pain, achilles tendonitis, bunions, shin pain, tired, aching legs, knee pain and lower back pain. The most effective treatment solution for over-pronation is wearing an orthotic shoe insert. Orthotics correct over-pronation, thereby providing natural, lasting pain relief from many common biomechanical complaints.
In addition to problems overpronation causes in the feet, it can also create issues in the calf muscles and lower legs. The calf muscles, which attach to the heel via the Achilles tendon, can become twisted and irritated as a result of the heel rolling excessively toward the midline of the body. Over time this can lead to inflexibility of the calf muscles and the Achilles tendon, which will likely lead to another common problem in the foot and ankle complex, the inability to dorsiflex. As such, overpronation is intrinsically linked to the inability to dorsiflex.
If you cannot afford to get a proper gait analysis completed, having someone observe you on a treadmill from behind will give you an idea if you are an overpronator. It is possible to tell without observing directly whether you are likely to be an overpronator by looking at your foot arches. Check your foot arch height by standing in water and then on a wet floor or piece of paper which will show your footprint. If your footprints show little to no narrowing in the middle, then you have flat feet or fallen arches. This makes it highly likely that you will overpronate to some degree when running. If you have low or fallen arches, you should get your gait checked to see how much you overpronate, and whether you need to take steps to reduce the level to which you overpronate. Another good test is to have a look at the wear pattern on an old pair of trainers. Overpronators will wear out the outside of the heel and the inside of the toe more quickly than other parts of the shoe. If the wear is quite even, you are likely to have a neutral running gait. Wear primarily down the outside edge means that you are a supinator. When you replace your running shoes you may benefit from shoes for overpronation. Motion control or stability running shoes are usually the best bet to deal with overpronation.
Non Surgical Treatment
There are exercises that you can do to help deal with the effects and treat the cause. Obviously you can opt for an insert into your shoe either by way of your sports shop or go see a podiatrist. Like anything in your body that is not working correctly; you will have to manage your condition. Don't put off dealing with the problem as it will manifest associated issues along the alignment and as far up as your neck. If it's mild pronantion, I suggest running barefoot. If you can't do this then don't wear shoes at all at home or in the office as much as possible. Give your calf muscles a huge stretch everyday as these with the ligaments from the foot up to the muscle get tight and are linked to your pain. Loosen your calf muscles as much as possible. Great exercise is to sit barefoot with a marble on the floor in front of you. Grab the marble with your toes and try to hold it tight in the middle of the base of your foot. Ping pong balls and even golf balls work. Do this each night and combined with calf stretches you'll start to correct the muscle alignment gradually in the foot. Put more attention into massaging your feet, standing with a good posture, stretching your feet, ankles and calf muscles. Lastly, if you are fat this will not help at all. You must lose weight swimming, cycling and eradicating sugar and fat from your diet. The added strain on the foot by being a fat body compounds the problems and inhibits corrective results that you are after.
Depending on the severity of your condition, your surgeon may recommend one or more treatment options. Ultimately, however, it's YOUR decision as to which makes the most sense to you. There are many resources available online and elsewhere for you to research the various options and make an informed decision.
