Foot types can be divided into three major groups: the flat foot (Pes Planus), the high arched foot (Pes Valgus) and the normal to low arched foot. A true 'flat foot' is very rare. In fact, less than
5% of the population have flat feet i.e. a foot with no arch present whatsoever and the entire bottom surface of the foot being flat on the ground. About 5-10% of people have a high arched foot. The
majority of the population have a normal to low arch. Even though the arches appear to be normal most of us suffer from over-pronation during walking, running and standing, due to the hard, flat
unnatural surfaces we walk on, combined with wearing unsupportive footwear. With every step we take the arches flatten and the ankles roll inwards. Pronation itself is not wrong because we need to
pronate and supinate as part of our natural gait cycle. Pronation (rolling in) acts as a shock-absorbing mechanism and supination (rolling out) helps to propel our feet forward. Over-pronation occurs
when the foot pronates too deep and for too long, not allowing the foot to 'recover' and supinate. Over-pronation hampers our natural walking pattern. It causes an imbalance and leads to wear and
tear in several parts of the body with every step we take.
It is important to identify the cause of overpronation in order to determine the best treatment methods to adopt. Not all treatments and preventative measures will work equally well for everyone, and
there may be a little trial and error involved to get the best treatment. A trip to a podiatrist or a sports therapist will help you to establish the cause of overpronation, and they will be able to
tell you the best treatments based on your specific degree of overpronation and the cause. Overpronation has many causes, with the most common reasons for excessive pronation listed, low arches,
flexible flat feet, fallen arches, gait abnormalities, abnormal bone structure, abnormal musculature, bunions, corns and calluses.
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.
Do the wet foot test. Get your feet wet and walk along a paved surface or sand and look at the footprints you leave. If you have neutral feet you will see a print of the heel with a thin strip
connecting to your forefoot, but if you're overpronating your foot print will look a bit like a giant blob with toes.
Non Surgical Treatment
Over-Pronation can be treated conservatively (non-surgical treatments) with over-the-counter orthotics. This orthotics should be designed with appropriate arch support and medial rear foot posting to
prevent the over-pronation. Footwear should also be examined to ensure there is a proper fit. Footwear with a firm heel counter is often recommended for extra support and stability. Improperly
fitting footwear can lead to additional foot problems. If the problem persists, consult your foot doctor.
The MBA implant is small titanium device that is inserted surgically into a small opening between the bones in the hind-mid foot: the talus (ankle bone) and the calcaneus (heel bone). The implant was
developed to help restore the arch by acting as a mechanical block that prevents the foot from rolling-in (pronation). In the medical literature, the success rate for relief of pain is about 65-70%.
Unfortunately, about 40% of people require surgical removal of the implant due to pain.
