Thanks for your comment. 2D video analysis can go a really long way in figuring out your patterns. If you have a mobile phone which can film slow-motion (all the new iPhones from 6 onwards), then you can record yourself running. Run on a treadmill for ease of use.

Run with and without shoes to compare differences. Make sure to run a few minutes to familiarise first.

Then practice barefoot for a few weeks, slowly increasing your volume. Film again and compare from weeks prior. I think this experiment could be really insightful.

I would love to hear about your results.
