I was wondering if anyone has any advice about how to deal with foot pain while exercising. My right food gets sore when I do weight-bearing exercise such as using the treadmill or playing squash, which are both cardio activities I do regularly. It is pain in the arch and ball of my foot. I am guessing it is probably my foot saying "please refrain from repeatedly pushing 270+ lbs down on me".....

but to that I say, giving it up is not an option! Especially squash, which I have grown to love.
I know you guys aren't doctors but have any of you experienced this? I bought some new running shoes and the problem has not gone away. I was thinking maybe I could get those gel insoles or something.
