Just some observations,
Just some observations, because i had the toe thing happen to me last week so i started paying attention to my body position while i'm running. For me, i'm finding that i tend to favor my right foot and i'm pushing rather than lifting. That's currently the reason that my pads are sore. The next thing that i noticed was that as i got tired, i slouched. My shoulders rolled forward and my back hunched over just a bit. I think this is causing my center of gravity to shift forward and with me favoring the right foot, my foot is rolling off more towards the 'ring toe' than forward towards the big toe.
I think that barefoottyler got it right with pushing the chest out and tilting the pelvis. As soon as I realized i was slouching and remember to straighten up, i could tell that the direction my foot rolled had shifted. Rather than rolling out, it was rolling more forward. I still need to work on lifting that foot though.
