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, potentially causing severe
discomfort and leading to other foot problems.
Over-pronation is very prominent in people
who have flexible, flat feet. The framework of the foot begins to
collapse, causing the foot to flatten and adding stress to other parts of
the foot. As a result, over-pronation, often leads to Plantar Fasciitis,
Heel Spurs, Metatarsalgia, Post-tib Tendonitis and/or Bunions.
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
Treatment and Prevention
Over-Pronation can be treated
conservatively (non-surgical treatments) with over-the-counter orthotics.
These orthotics should be designed with
appropriate arch support and medial rearfoot 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.
