Normally, when you walk or run, your heel is the first part of your foot to strike the ground. As your body weight shifts to the middle of the foot, the arch of the foot naturally flattens out a bit.
This flattening is called pronation. If your feet flatten more than normal, it?s called over-pronation or flat feet. Over-pronation can cause many problems, such as an Achilles tendon injury or heel
pain. It may lead to knee problems.
Flat feet don't automatically mean you have a problem. The problem can be divided into a flexible flat foot or rigid flat foot. The rigid flat foot is one that does not change shape when the foot
becomes weight bearing. i.e. it does not go through the excessive motion of pronation. Generally speaking this foot does not provide too many problems. The flexible flat foot is the type that when it
becomes weight bearing the foot and ankle tends to roll in (pronates) too far. This type of person will often say I have great arches but when I stand up much of this arch disappears as the foot
excessively pronates When the foot is excessively pronating and causing problems like sore ankles, feet or knees when standing or exercising then arch support is extremely important to restore the
If you overpronate, your symptoms may include discomfort in the arch and sole of foot, your foot may appear to turn outward at the ankle, your shoes wear down faster on the medial (inner) side of
your shoes. Pain in ankle, shins, knees, or hips, especially when walking or running are classic symptoms of overpronation. Overpronation can lead to additional problems with your feet, ankles, and
knees. Runners in particular find that overpronation can lead to shin splints, tarsal tunnel syndrome, plantar fasciitis, compartment syndrome, achilles tendonitis, bunions or hallux valgus,
patello-femoral pain syndrome, heel spurs, metatarsalgia.
At some point you may find the pain to much or become frustrated. So what are you options? Chances are your overpronation has led to some type of injury if there's pain. Your best bet is to consult
with someone who knows feet. Start with your pediatrist, chiropodist or chiropractor. They'll be able to diagnose and treat the injury and give you more specific direction to better support your
feet. One common intervention is a custom foot orthotic. Giving greater structural support than a typical shoe these shoe inserts can dramatically reduce overpronation.
Non Surgical Treatment
Personal orthotics can be prescribed via your healthcare professional. If finances or insurance are issues, similar and often better options can be purchased online for overpronation. The right
walking shoes are also essential. Most shoes cater to neutral foot gaits, unless they specifically state otherwise. That won?t help you if your foot rolls inward. In order to correct the issue, you
need shoes with stability or motion control abilities, low heels, deep heel cups, and good arch support.
Subtalar Arthroereisis. The ankle and hindfoot bones/midfoot bones around the joint are fused, locking the bones in place and preventing all joint motion. This may also be done in combination with
fusion at other joints. This is a very aggressive option usually reserved for extreme cases where no joint flexibility is present and/or the patient has severe arthritic changes in the joint.
