How to start barefoot running
Start with thirty minutes of barefoot activity a day for 3-4 weeks.
This will give your feet a chance to develop thicker skin for running at higher speeds and for longer times. Start by just walking, then jogging, then running, but limit the activity to thirty minutes a day at first.
If you transition too quickly, you may develop plantar fasciitis. Walk for a few minutes to allow your feet to get familiar with the surface.
