Thought people may be interested in what Kelly Starrett of Crossfit fame has rto say on feet. Hope I have this video embedded correctly.



if not heres the link. http://youtu.be/ha6ZxfG6Tz8

 

..never let the facts get in the way of a story!

Reminds me of Steve Magness from the Science of Running what he wrote back in June about Crossfit: How to spot bad science and fads- Determining whether an idea is worthwhile:

Highly recommend everyone read it. Also those who really need to read it, when they do, they do not get it (HINT: read the comments)

 

Thanks for that link Craig, very interesting, sure it could be applied to many other subjects (including some on here;))

 

The sad thing is that the people that really need to read that article and take on board what it says are the ones that are less likely to read it and if they do happen to read it, they are less likely to realize that it actually applies to them!

Its like Payne's first law: The amount of passion and emotional attachment to a theory is inversely proportional to the evidence for that theory ...... those that the law applies to are less likely to realize that

 

Craig, what are your thoughts regarding running or walking with your feet positioned so that your toes point straight forward vs pointing outward or inward? Which position of the feet is most stable and mechanically sound?

During running and walking the feet are not stable, nor is this desirable, hence we see movement at the pedal joints.

 

As with the wearing of shoes, it depends. There is no best angle for all people. Angle of gait is in part determined by hip range of motion and the torsion of the bones. There are individuals who have a hard time getting there foot, within their available range of motion, to a point that is straight ahead. Some of all those people will be all internal and some of those people will only be externally rotated. I've though about it a little bit and I don't think the angle of the foot to the line of progression will change the mechanics of the foot that much. I believe that there are other factors that will have a bigger mechanical influence. I'd be willing to listen to people's theories on how angle of gait effects foot mechanics.

Simon, thank you. A very interesting paper.
