After my last couple of HIIT sessions my calves have been hurting to the point where im hobbling...not terrible pain but enough to make me stop running. I have been running in cheap Dunlop walking shoes, I think this could be the problem. Today I tried out my dads running shoes and they were better, though i still felt the pain afterwards which i think could be due to only 24 hours rest since the HIIT session. It would be hard to answer over the internet but do you think this pain could be due to the shoes? And what can I do to stop it?
