Thanks again for the response. I live in North America. With winter starting, barefoot running would be an issue. Can I sprint train on regular running shoes? Any other alternative?
After doing the recommended exercise just a couple of times, I am more aware of the placement of my foot. When doing my regular body stretches, I try to tilt my feet outwards a little so that the weight is distributed in the outer edge and small toes more than the arch(flat). Not sure if this is good or bad.
