If the inner side of your shoes are especially worn, you could be overpronating. Excessive inward roll of the foot after landing, such that the foot continues to roll when it should be pushing off.
This twists the foot, shin and knee and can cause pain in all those areas. If you are an overpronator, you'll find excessive wear on the inner side of your shoes, and they'll tilt inward if you place
them on a flat surface. Knock knees or flat feet contribute to overpronation.
There are many possible causes for overpronation, but researchers have not yet determined one underlying cause. Hintermann states, Compensatory overpronation may occur for anatomical reasons, such as
a tibia vara of 10 degrees or more, forefoot varus, leg length discrepancy, ligamentous laxity, or because of muscular weakness or tightness in the gastrocnemius and soleus muscles. Pronation can be
influenced by sources outside of the body as well. Shoes have been shown to significantly influence pronation. Hintermann states that the same person can have different amounts of pronation just by
using different running shoes. It is easily possible that the maximal ankle joint eversion movement is 31 degrees for one and 12 degrees for another running shoe.
Eventually, over-pronation can lead to a full list of maladies including flat feet, plantar fasciitis, plantar fibroma, neuromas, heel spurs, shin splints, ankle sprains, bunions, hammertoes,
calluses, and pain in the arches, knee, hip and lower back. But it doesn?t have to go that far, because there are steps we can take to correct the over-pronation. In the vast majority of cases, we?ll
prescribe custom foot orthotics, which will realign your ankles, redistribute the weight, support the arch and reduce the twisting. Many orthotics will fit snugly into your normal shoes. Although
we?ll also take a look at the type of shoes you wear to see if they are contributing to the problem.
When sitting, an over-pronating foot appears quite normal, i.e. showing a normal arch with room under the underside of the foot. The moment you get up and put weight on your feet the situation
changes: the arches lower and the ankle slightly turns inwards. When you walk or run more weight is placed on the feet compared to standing and over-pronation will become more evident. When walking
barefoot on tiles or timber floors over-pronation is more visible, compared to walking on carpet or grass.
Non Surgical Treatment
Overpronation of the feet can be corrected in some cases and in others it can be effectively managed. Overpronators can train themselves to change their running gait, wear arch supports, orthotic
insoles or specialist shoes for overpronators. In order to determine exactly what is happening during the stride, it is necessary to have a gait analysis conducted by a professional. The extent of
overpronation can then be determined, and the causes can be identified and corrected directly. The main corrective methods used for excessive pronation are orthotics. Orthotics are the most
straightforward and simplest solution to overpronation. Orthotics are devices which can be slipped into shoes which will offer varying degrees of correction to the motion of the foot. Orthotics help
to support the arches and distribute the body weight effectively, and are usually the best treatment choice for moderate to severe overpronation. Orthotics may require existing insoles to be removed
from your shoes to accommodate them; although most running shoes will have a removable insole to accommodate an orthotic insole.
Subtalar Arthroereisis. Primary benefit is that yje surgery is minimally invasive and fully reversible. the primary risk is a high chance of device displacement, generally not tolerated in
An implant is pushed into the foot to block the excessive motion of the ankle bone. Generally only used in pediatric patients and in combination with other procedures, such as tendon lengthening.
Reported removal rates vary from 38% - 100%, depending on manufacturer.
