Alas, those type of clinical trials are extremely rare. IF you find anything at all close, it would be extremely interesting. The quote from daily mail about percentage of weight on ball of foot is extremely suspect as they are almost enquirer source.

I have an appt with spine doctor tomorrow and plan on posing question to him, but thought it might be good to have some real world input.

Thanks
