Overview
Over-pronation, or flat feet, is a common biomechanical problem that occurs in the walking process when a person?s arch collapses upon weight bearing. This motion can cause extreme stress or inflammation on the plantar fascia, possibly causing severe discomfort and leading to other foot problems.
Causes
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 foot structure.
Symptoms
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.
Diagnosis
You can test for pronation by looking at the leg and foot from the back. Normally you can see the Achilles Tendon run straight down the leg into the heel. If the foot is pronated, the tendon will run straight down the leg, but when it lies on the heel it will twist outward. This makes the inner ankle bone much more prominent than the outer ankle bone.
Non Surgical Treatment
Adequate footwear can often help with conditions related to flat feet and high arches. Certified Pedorthists recommend selecting shoes featuring heel counters that make the heel of the shoe stronger to help resist or reduce excessive rearfoot motions. The heel counter is the hard piece in the back of the shoe that controls the foot?s motion from side-to-side. You can quickly test the effectiveness of a shoe?s heel counter by placing the shoe in the palm of your hand and putting your thumb in the mid-portion of the heel, trying to bend the back of the shoe. A heel counter that does not bend very much will provide superior motion control. Appropriate midsole density, the firmer the density, the more it will resist motion (important for a foot that overpronates or is pes planus), and the softer the density, the more it will shock absorb (important for a cavus foot with poor shock absorption) Wide base of support through the midfoot, to provide more support under a foot that is overpronated or the middle of the foot is collapsed inward.
Surgical Treatment
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.
