Simply put, over-pronation is an excessive or poorly timed pronation which is part of the regular stride. Pronation is when the foot rolls inwards and the arch compresses as part of your normal
walking motion. Pronation is necessary for shock absorption to transmit forces up and down our legs. When someone over-pronates, the foot rolls inwards to a greater degree and the arch flattens: this
causes the knee and hip to come out of alignment and reduces the function of all the bones in the feet.
There are many causes of flat feet. Obesity, pregnancy or repetitive pounding on a hard surface can weaken the arch leading to over-pronation. Often people with flat feet 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.
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 Facsitus). Metatarsalgia (ball of the foot pain). Ankle Sprains. Shin Splints. Achilles Tendonitis.
Osteochondrosis. Knee Pain. Corns & Calluses. Flat Feet. Hammer Toes.
To easily get an idea of whether a person overpronates, look at the position and condition of certain structures in the feet and ankles when he/she stands still. When performing weight-bearing
activities like walking or running, muscles and other soft tissue structures work to control gravity's effect and ground reaction forces to the joints. If the muscles of the leg, pelvis, and feet are
working correctly, then the joints in these areas such as the knees, hips, and ankles will experience less stress. However, if the muscles and other soft tissues are not working efficiently, then
structural changes and clues in the feet are visible and indicate habitual overpronation.
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.
Custom-made orthotics will reduce the twisting of the leg muscles as they enter the foot, by maintaining a normal alignment of the bones and joints of the foot. If the bones and joints are aligned
properly, by reducing the pronation, the muscles can run straight to their attachments in the foot, without twisting to get to these bones. This action of custom-made orthotics will reduce Achilles
Tendonitis shin splints; ankle, knee, hip, and lower back pain; and leg cramps. This action will also allow the leg muscles to work more efficiently, thus allowing you to walk and run with less
