I was merely calling for sympathy out of my sport war scares ;-)
Feets are indedd delicate things, and the smallest bone displacement can create huge problem for running.
I see we are about the same size and weight, but you are stilla young chap.
For me, it's impossible to run too long now, slim or not, it's still a lot of weight on feets when you compare to maratoner typical weight.
If I jog more than half an hour, I start to feel all sort of pain under my feets, mix of upset tendons and metacarpe articular pain.
As you run a lot, you definitly need to to choose your sport shoes like a future bride, and test many of them to correct any pronation/suspination tendency.
See also if you can get advice from an expert track coach. Running is natural and all, but most people do it really wrong. Even competitive long distance runner display big techincal flaws.... As long as you are young, and not too heavy, it will damage you slow enough that you won't get problem before retirement. But if you are heavier, or run really a lot, the small traumatismes on each impact of the feet on the ground accumulate and at one point, you get problems.
A flawless strike is a lot more effective to prevent foot injuries than any shoes or corrective sole.
