Painful Feet: Might be related to pedal-foot positioning Sometimes when I set out on a ride I will get the absolute worst foot pain. It is like a cramp in my arches on both feet.

I am wondering where exactly the center of the pedal should fall in relation to my foot.
Definitely open to debate. Steve Hogg has some good information about cleat position.

and arch supports.

I suffered from something called hot foot and using corrective insoles relieved me of all pain.
