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.
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
Common conditions seen with overpronation include heel pain or plantar fasciitis, achilles tendonopathy, hallus valgus and or bunions, patellofemoral pain syndrome, Iliotibial band pain syndrome, low
back pain, shin splints, stress fractures in the foot or lower leg.
So, how can you tell if you have overpronation, or abnormal motion in your feet, and what plantar fasciitis treatment will work to correct it? Look at your feet. While standing, do you clearly see
the arch on the inside of your foot? If not, and if the innermost part of your sole touches the floor, then your feet are overpronated. Look at your (running/walking) shoes. If your shoes are more
worn on the inside of the sole in particular, then pronation may be a problem for you. Use the wet foot test. Wet your feet and walk along a section of pavement, then look at the footprints you leave
behind. 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.
Non Surgical Treatment
Get a gait analysis of your running style, this will highlight if you overpronate, oversupinate or have a neutral gait. Most podiatrists, physio's and sports therapists will offer this service, as do
some specialist sports shops. Find a clinic. If you overpronate, get orthotics with extra medial support. Many running shoes have a harder material on the inside of the midsole (the thick hard foam
part of the running shoe). This means the inside of the shoe will be compressed less under load and support the inside of the foot preventing it from rolling in or flattening. For people with
considerable overpronation, another option is to have an orthotic device fitted. Orthotic insoles come in many types and prices. Some are pre-molded and can be bought off the shelf. These are ok for
the majority of problem feet. However some cases may require specially casted orthotics from a relevant sports injury therapist or podiatrist.
HyProCure implant. A stent is placed into a naturally occurring space between the ankle bone and the heel bone/midfoot bone. The stent realigns the surfaces of the bones, allowing normal joint
function. Generally tolerated in both pediatric and adult patients, with or without adjunct soft tissue procedures. Reported removal rates, published in scientific journals vary from 1%-6%.
