Hi all. I seem to suffer terribly with a weak left calf - especially if I've had a bit of time off. I always warm up and cool down thoroughly and I use a foam roller to loosen it up (which takes my breath away it hurts so much). I run in minimal shoes and concentrate on mid foot strike but more often than not the day after a run my left calf is cramping and causing me grief. Any advice greatly appreciated. Thank you!
