Very interesting article in this months Lower Extremity Review on testing running shoes.

http://lowerextremityreview.com/article/a-three-point-approach-to-testing-running-shoes

 

Maybe that should be used to check some of the football boots our pro's are using....l dont think too many would pass the test

 

that is one of the biggest problems with soccer, rugby and any cleated shoes on the market. Given the potential risks of knee, hip and ankle compensations due to allowing free midfoot / MTJ compensations coupled with FF dorsiflexion you can see why so many injuries may commonly occur and be potentially related to footwear.

I hear that he refers to stability, therefore does he only apply these rules to ‘stability/motion control’ shoes or does he apply these rules to ‘cushion’ shoes as well?

I think a forth and very important point is also worthy of a mention, it applies to all types of running shoes. The integrity of the upper; it needs to have parity with the sole unit.

A sole unit for a motion control shoe needs an upper that has support woven into it so can cope with the forces being applied to it – generally in this instance from foot with excessive pronation (to use an umbrella term),

Likewise a sole unit for a cushion shoe can get away with a lightweight fabric upper as the foot predominately is rigid.

 

Can we extrapolate from forefoot data to midfoot? Forefoot data shows that: "since forefoot stiffness and shoe bending stiffness act in parallel (i.e., are additive), the total forefoot stiffness of the shod foot is dominated by that of the human foot.http://www.sciencedirect.com/scienc...serid=10&md5=ace36d27bbfe77e7c9242aa443e4cb41

If the same is true for the midfoot, then the total stiffness of the midfoot should be dominated by that of the human foot in shoes like this. Food for thought?

 

l agree, the shoe/boot here is offering nothing to the foot except for a covering or is it, with such a soft flexible upper and sole if it was laced up firmly is it now offering a similar effect to that of low dye taping? ...still not enough and the foot is still going to dominate what happens be it good or bad.
