I've got a similar problem but I seem to get the problem when actually running. I went to the Physio last week after trying stretching, foam rolling, heel drops/raises, compression sleeves etc for a good 12 months now.
She came to the conclusion that my tight back muscles along with weak glutes were contributing to the problem. Lots of stretching for a few weeks and we'll see what happens.....
Kind of disappointing as I thought I'd got more flexible and stronger recently but her face when assessing range of movement left me under no illusions to the fact I've got lots of work to do!
