Overpronation is a expression that produces plenty of angst among podiatric doctors and running shoe shops mainly because it brings about a huge amount of misunderstandings and controversy. Pronation is a movement of the foot where the ankle rolls inwards and the arch of the foot collapses. This is the normal healthy motion that is required for normal foot biomechanics and shock reduction. Overpronation is said to be the word helpful to identify should there be an excessive amount of this normal pronation. The initial aspect of the debate is precisely what is normal and what's abnormal and where may be the threshold of the division between normal pronation and overpronation. You will find robust opinions on every side of this debate and there doesn't appear to be any resolution in the controversy coming.
The key reason why the subject produces a huge amount of dialogue is that overpronation has been considered a major aspect in overuse injuries in athletes. Podiatric doctors frequently use foot orthoses to treat the condition and running shoe manufacturers make running shoes to help athletes that have the problem. This means there is lots of vested interest in this. The problem arises is that the scientific evidence shows that, yes, overpronation might be a risk factor for a running injury, but it is not really a large risk factor. It's even more complex by a lot of runners who may have fairly severe overpronation and never develop any problems and never need foot supports or running shoes with the motion control design features. That does not help resolve the controversy nor help clinicians make decisions re foot orthoses and for running footwear merchants on advice as to what needs to be the right running shoe. It really comes down to clinicians and running shoe retailer’s individual experience and expertise and making choices in the context of what exactly is ideal for the individual athlete.
