Overpronation is a expression that triggers lots of angst among podiatrists and running shoe shops as it causes a whole lot of misunderstandings and controversy. Pronation is actually a movement of the foot where the ankle rolls inwards and the mid-foot (arch) of the foot flattens. This is the normal healthy movement which is necessary for normal foot biomechanics and impact moderation. Overpronation is meant to be the term useful to identify if you have an excessive amount of this normal pronation. The first aspect of the controversy 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 views on every side of this controversy and there does not appear to be any resolution in the discussion on the horizon.
The key reason why the subject produces a huge amount of debate is that overpronation continues to be thought to be a major factor in overuse injuries in runners. Podiatrists frequently use foot supports to deal with the problem and running shoe manufacturers design running shoes to help athletes which have the condition. This implies there is a lot of vested interest in this. The issue arises is that the scientific evidence shows that, yes, overpronation can be a risk factor for a running injury, but it is not much of a significant risk factor. It's additionally complicated by a lot of athletes who have pretty severe overpronation and do not develop any problems and never need foot orthotics or running shoes using the motion control design features. That will not help solve the controversy nor help clinicians make judgements re foot orthotics and for running footwear merchants on advice in regards to what should be the right running shoe. It really is dependant on clinicians and running shoe retailer’s individual experience and expertise and making conclusions in the context of what exactly is ideal for the individual athlete.
