Overpronation is by far the most common foot type. Pronation is not linked one-to-one with low arches. Although pronation lowers the arches, this does not mean that only those with low arches
overpronate. People with high arches can also overpronate! Some of us have always overpronated, for others overpronation develops with age, weight gain, regular standing work or intensive exercise.
Pronounced wear on the instep side of shoe heels can indicate overpronation, however it's best to get an accurate assessment.
There is a relationship between biomechanics and injury that is specific to each body part. Overall though, poor mechanics will either increase the landing forces acting on the body or increase the
work to be done by the muscles. Both increase the stress, which, depending on the individual and the amount of running can become excessive and cause injury.
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.
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
Pronation and supination are bio-mechanical problems, and are best treated and prevented with orthotic inserts. But before you run out to buy orthotics it makes sense to get the right advice on
footwear, and the best advice I can give you, is to go and see a qualified podiatrist for a complete foot-strike and running gait analysis. They will be able to tell you if there are any concerns
regarding the way your running gait is functioning. After your running gait has been analysed, have your podiatrist, or competent sports footwear sales person recommend a number of shoes that suit
your requirements. Good quality footwear will go a long way in helping to prevent pronation and supination. And, if needed, invest in a pair of orthotic inserts to further prevent excessive pronation
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
