Thanks for the reply.
Yes, over pronation does seem to be implicated in runners and I’m not sure to what extent it applies to cyclists. I suppose flat-ish arches and no arch support in the cycling shoes might not help (one of the roles of the post tib tendon is maintaining the medial arch). Hopefully the orthotics I’m using will address this and allow it to rest/heal. I hope your daughter has fully recovered!
I’ve had no changes in my (professional physio-led) bike fit recently and sadly I’ve moved city from the very good physio bike fit place I previously attended.
This hit me out of nowhere but has opened by eyes to the concept of pre-hab where I had previously done no flexibility work etc and hadn’t considered my shoewear etc. I’d encourage all cyclists to do some flexibility work and consider visiting a podiatrist before you get problems. It is incredible to read on the forum that people with fibular fractures were off the bike for 6 weeks whereas my trivial tendon inflammation has had me off for nearly double that and it’s still not healed.
