Overpronation is a phrase that produces a great deal of angst among podiatric doctors and running shoe shops because it brings about a huge amount of misunderstandings and debate. Pronation is actually a motion of the foot in which the ankle rolls inwards and the arch of the foot flattens. This is a normal healthy motion that is essential for normal foot biomechanics and shock reduction. Overpronation is said to be the term useful to explain when there is an excessive amount of this normal pronation. The initial aspect of the debate is precisely what is normal and what is abnormal and just where is the threshold of the division between normal pronation and overpronation. You can find strong opinions on every side of this controversy and there does not seem to be any resolution in the discussion coming.
The reason this issue produces so much dialogue is that overpronation has been considered a primary factor in overuse injuries in runners. Podiatric doctors frequently use foot orthotics to deal with the issue and running shoe manufacturers design running shoes to help runners that have the problem. This suggests there is lots of vested interest in this. The problem arises is that the scientific evidence demonstrates that, yes, overpronation might be a risk factor for a running injury, however it is not much of a big risk factor. It can be additionally complicated by a lot of athletes who have pretty extreme overpronation and do not develop any issues and never need foot orthoses or running shoes using the motion control design characteristics. That doesn't help solve the controversy nor help clinicians make decisions re foot orthoses and for running shoe merchants on advice as to what ought to be the right running shoe. It really is dependant on clinicians and running shoe retailer’s individual expertise and experience and making conclusions in the context of what exactly is best for the individual athlete.
