I am not surpised that the Podiatrists did not know about Chi Running. I have heard of it, but do not know a lot about it, so looked it up. It is a technque that uses a forefoot strike as opposed to the more common heel strike. My understanding of running biomechanics is that it takes energy to change and the most efficient style is usually the natural one. There are a lot of ideas, such as Chi, Pose and Barefoot with them all claiming to be more efficient, but the research does not support that.
If the Chi Running is causing pain in the forefoot, then if you do not have a compelling reason to keep running that way, then maybe reverting to heel stike may be a good idea. Without knowing the specific diagnosis that you have, it is a bit hard to give any more specific advice.
What shoes are you using?
I found this on a chi running which may or may not help you and I though this opinion on chi running was helpful. I learnt a lot from these chi running videos.
