I want to again stress the importance of transitioning into barefoot training and running. Many people are getting injured by not listening to their body. There is a difference between working until pain and working through the pain. We all can be hard headed and determined, but I would much rather see someone take it slow and steady versus having to recover from going too far too fast. It is a sign of strength to honor your body.
Now with that said, I challenge you to strengthen your feet by going for a walk in the park, or spend one hour more than you normally would barefoot!
