Hi.
I suffer from this from time to time.
Got it real bad a few years ago, when i took up running. Thankfully, with a few weeks of physio, I was back running and cycling in no time. But its always a weakness I've got.
Just have to remember to do the right stretches.
My feet overpronate, so I have to have special shoes for running. I really should look at what I'm wearing for cycling, but cycling doesn't really affect me that way running does.
Anyway, if you have a bit of money available, having a sports physio appointment is well worth it.
Good luck
