Hi Monty
I will have a look at the Asics - thank you. But I could not find the Kahuna Trail Runner on their web site.
> mids rub and absorb energy That's MY experience. But I am referring to the bit around the ankle, not to the sole. I find that a significant ankle cuff rubs my ankle and I can feel that it is resisting my ankle bending. This goes to an extreme with the high boots of course. They are a left-over of the old leather army boots era.
> shoe arch being detrimental to the point of being injurious. OK, this is one of those delightfully vague areas. The term 'arch support' itself derives entirely from Nike marketing of a couple of decades ago - an inspired bit of unjustified foot-destruction which has caused huge problems for athletes around the world. It is now recognised as being actively dangerous to your foot health.
Originally leather shoes had virtually no side-incut at the arch at all, partly because it was hard to do. And the inner sole was dead flat. All moulded soles now have some side-incut at the arch region to help retain the foot in the 'right' position for the shoe. Some manufacturers refer to this side-incut as the 'arch support', but the term is misused. We just don't have an alternative!
My venom towards 'arch supports' is directed at the idea that the sole should rise up UNDER the foot to 'support' the arch. This is a criminal concept. Nike's justification for this when they introduced it was the idea that your foot was not strong enough to support itself. There was no medical research behind this and no bio-medical justification for it. It was just a marketing idea, but they fooled the world for some years.
The effect of something under the arch of your foot is to cause compression on the tendons under your foot, while they are working hard. You should think of them as the string on a tensioned bow, with the bones of your foot being the bow itself. This compression on hard-working tendons causes bruising and can cause the sheath around the tendon to be abraded away and start leaking. Your tendons then lose their lubrication and can rub raw. This leads to Repetitive Strain Injury (RSI), and can be crippling. As I said, it is a criminal concept.
> I have absolutely flat feet This is another stupid marketing concept. Your feet have a certain structure from your genetics. There is NOTHING wrong with your feet! Do NOT believe any marketing ******* which implies otherwise!
(Before anyone pitches in with a foot problem which has been diagnosed by a qualified podiatrist, let me state that I am not talking about such genuine problems. I am talking about ordinary healthy feet.)
However, it may be that the construction of the sole of the shoes you are wearing is mismatched to the shape of your feet. Fair enough: feet do vary widely in shape. If wearing Superfeet insoles improves the match then you have the perfect justification for wearing them (COMFORT!).
:-)
cheers
