Overpronation, 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.
Overpronation 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 overpronation. 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.
Overpronation can be treated conservatively with carefully designed orthotics. These orthotics should be designed with appropriate arch support and medial rearfoot posting to prevent the over-pronation. Archline products are specially designed to prevent overpronation.
