Overpronation is a term that triggers a lot of concern among podiatrists and running shoe retailers because it causes a huge amount of misunderstandings and controversy. Pronation is a movement of the foot where the ankle rolls inwards and the mid-foot (arch) of the foot collapses. This is the normal healthy movement that is necessary for normal foot biomechanics and impact moderation. Overpronation is said to be the term used to identify if you have too much of this normal pronation. The initial aspect of the controversy is just what is normal what is actually abnormal and exactly where would be the threshold of the split between normal pronation and overpronation. There are strong opinions on all sides of this argument and there doesn't seem to be any resolution in the debate on the horizon.
The reason why this issue produces a great deal of dialogue is that overpronation has been regarded as a key factor in overuse injuries in athletes. Podiatrists commonly use foot orthotics to treat the condition and running shoe producers make running shoes to help athletes that have the problem. This suggests there is a lot of vested interest in this. The problem arises is that the scientific evidence shows that, yes, overpronation may be a risk factor for a running injury, however it is not a big risk factor. It's additionally complex by a lot of athletes who have quite severe overpronation and do not develop any issues and do not need foot orthotics or running shoes with the motion control design features. That does not help take care of the controversy nor help clinicians make judgements re foot supports and for running footwear shops on advice in regards to what ought to be the appropriate running shoe. It really comes down to clinicians and running shoe retailer’s individual expertise and experience and making conclusions in the framework of what is suitable for the individual athlete.
