I started having foot pain mainly this year on the balls of my feet... I also notice that the more I ride the cat tracks on my toe side (I'm regular) the worse the pain was. Long traverses on my toe side and the pain would start and boy, once it started it just got worse and worse to the point that I had to stop and rest and then start again.
Thought I would update since I was getting very similar pain to you. My foot pain appears to be pretty much gone now. The two things that changed were 1) I changed from a forward stand (15/6) to a duck stance (15/-6) and 2) I finally managed to start doing turns on cat tracks where I would previously have been stuck on toe side the whole time. Not sure which helped more.
