For the larger than average runner carrying more than an extra couple of pounds.
Can excessive weight exaggerate or cause pronation, due to the extra weight making the foot "flex" more ?
or am i making life too difficult ?

Regards steve.
apologies for being boring!
As for the arch supports, there good an do no harm. But the level of pronation is the same. It is only partially linked to arch height.
i appear to have stopped pronating so much
Well done to your mate though.
It just seems from casual observation at races that the fast runners are all in neutral shoes.
However it aint clear cut, and there is huge consensus as to the optimum required degrees of eversion(pronation) reuired for the normal gait. Also no person is mathamaticaly perfect in the way a machine is!
So, us over-pronators are not only more likely to get injured, but we're slower too (OK, maybe in no measurable way but...)
Levels of injury in pronated foot types is greater than in normal, and it depends on the reason for the pronation (remember the compensation bit) to how bad it is. One bad thing is a gastroc equinus/ankle equinus. Which means tight calfs in most cases. The resultant pronation as compensation is bad in many cases.
Lots of people have this equinus. If standing pull your foot so the thing is level and knees locked. eg not to flat but not on outside of feet. if you can rock forward with no tension so shin goes over ankle then cool, u need 10 degrees for normal gait. if not stretch. this is pprox though!
and yea chance would be a fine thing, david the mags pod should do it !
Also it is difficult to say if a foot is excessive pronation. it depends on where about the neutral is. if neutral is -7 degrees then 8 degrees pronation will take you to +1 degrees. so only just excessive pronation. The -7 degrees is a rear foot varus of 7 degrees. the amount of pronation is said to be excess of 1 degrees as 6 degrees is used to get to neutral, which is the ideal level of compensation for this deformity (Varus of 7 degrees, a varus at rear foot is another cause of pronation). if it gets to neutral or just before then the heel is vertical and this is the ideal. This is a partial compensated rear foot varus. As we have 1 degree left over in the example we go past neutral/vertical by 1 degree this is a fully compensated rear foot varus. wouldent usually bother treating such a little level, meausurements etc arent accurate enough. But if compounded by tight calf or an ankle that can not move upward enough, to allow the leg over the foot during midstance, the pronation in above example could be an extra 4 degrees that makes all the diffence. This is compensation by shortening the foot/leg to allow the leg over?(sorry about that). There are so many examples it isent as simple as above example and each case requires a thorough understanding of concepts to which can be added to over years of training. But hope above stands in good stead as an understanding to what people are/or think there going on about.
