Overpronation is a phrase that triggers a lot of angst among podiatric doctors and running shoe shops as it creates a huge amount of misunderstandings and debate. Pronation is a motion of the foot in which the ankle rolls inwards and the mid-foot (arch) of the foot collapses. This is the normal healthy motion that is essential for normal foot biomechanics and shock absorption. Overpronation is supposed to be the term helpful to describe should there be an excessive amount of this normal pronation. The initial part in the discussion is just what is normal and what's abnormal and exactly where could be the threshold of the division between normal pronation and overpronation. You can find formidable views on every side of this argument and there does not appear to be any resolution in the controversy on the horizon.
The key reason why the topic produces so much discussion is that overpronation continues to be thought to be a key factor in overuse injuries in athletes. Podiatric doctors frequently use foot orthoses to treat the problem and running shoe manufacturers make running shoes to help athletes which may have the problem. This signifies there is lots of vested interest in it. The issue arises is that the research evidence shows that, yes, overpronation is usually a risk factor for a running injury, but it is not really a large risk factor. It can be additionally complicated by a lot of athletes that have really extreme overpronation and never develop any issues and do not need foot orthotics or running shoes using the motion control design characteristics. That does not help solve the controversy nor help clinicians make choices re foot orthotics and for running footwear sellers on advice in regards to what should be the appropriate running shoe. It really comes down to clinicians and running shoe retailer’s individual expertise and experience and making choices in the context of precisely what is ideal for the individual runner.
