Fittit can I pick your brain? I have flat feet...

I am currently on a strength program. I was wondering what your thoughts were on training with flat feet. Should I be concerned with the heavy lifting I am doing in the long run? I don't let my knees track in while squatting but I just naturally have inward pronation on my ankles. It is never painful, but I wonder if I could be doing any damage as it seems like the mechanics of my feet must be acting differently than the norm.
