I have been running barefoot since about 2005 (and well before that as a child). I gave up running beyond 10 miles years ago just because it isn't of interest to me. I was a regular on the Yahoo group back in the day. However, just in the last year I have had a nagging strain in my calf. I am now running 6 or less miles. And often at just 2 miles one of my calves will get tight. I do warm up exercises before every run. I am not trying to run fast (7-10 min/mi depending on conditions). I run on a mix of hard (sidewalks and streets) and soft (trails) surfaces. I love running barefoot! And want to be able to run at a minimum a few miles. I'm starting to wonder if switching to shoes will allow me to avoid this pain/injury. At times I have taken days to weeks off out of convenience. It seems to go away to only creep back. If you have any insight you would be up for sharing I would appreciate it. I suppose getting therapy would be good?
