All the running shoes i look at are in three broad categories: shoes for over-pronation, shoes for
supination and shoes for "neutral" runners. Basically the three categories are to do with how your foot lands and takes off when running; whether you run on the outside or inside of your feet or "neutrally". The shoes have padding to address any over-pronation or supination.
Many runners swear by their shoes but I'm increasingly beginning to think in a lot of cases the shoes are treating the symptom rather than the cause. I run neutrally but after my last marathon I was told I with a slight over-pronation. But instead of buying different shoes I suspected the problem was not my feet but my tired glutes after the marathon. I went to the osteopath and did exercises to strengthen my glutes. Hey presto new analysis of my running and I'm back to running neutrally.
The analysis was correct, I was over-pronating, but I treated the cause rather than the symptom.
I'm sure there are lots of things wrong with my running I just hope I have the foresight to seperate the cause from the symptom and become a healthier runner.
In the meantime I will continue to wander around running sports shops and covet all the running shoes, whatever category they are in.
