Fibularis Peroneus Brevis
Sometimes a lightbulb comes on in my head and I realise why something is happening. For ages now my left foot has had problems. The latest is fibularis (Peroneus) Brevis.

The tendon on the edge of my foot hurts like hell – it joins up just on to the fifth metatarsal. I went running tonight and all was well, it is hurting like hell again now. I looked at my new shoes and could see an age old problem. Choose what shoes I wear, on the left one my foot sort of “falls off” the sole near the ball of foot and rolls onto the shoe upper. This is where I tend to destroy shoes. The problem becomes more acute when running faster but happens to some degree all of the time.
I had noticed on videos that my left foot flicks out while running – I think it lands or at least weights quite heavily with the foot still sort of flicked out. I looked at the diagram again and realised that the peroneaus muscle and tendon evert or flick out the foot. I have always said I cannot seem to get rid of tension in my left – no problems with the right. I know why now (hopefully)! I am landing with the foot everted or if not fully everted I have load on the tendon when I land and that is not good. This is why I have the injury! Landing with the tendon already loaded and then pulling it some more on landing…
Question is how on earth do I stop the foot from doing this? I did have some exercises given me ages ago – I’ll have a look at them. In the meantime if anyone knows how I can stop this please let me know…
I have since spoken to Cabletow – a sports injury doctor and Pose coach and this is what he said…
“in order for you to roll inwards the foot has already rolled out then comes back in under your bodyweight – what hurts that tendon is that you tense that muscle then the foot gets thrown out laterally then comes back in
I think it is that you are moving the leg through as a unit from the hip rather than pinging th foot up under you then it drops back down relaxed”
So I had it half right through observation of what is happening to the shoe and how it feels. There is some lateral scuffing on the shoe too which would support what Cabletow says. I’m still touching down on lateral edge, rolling inward and over. All I need to do is stop doing it.
I’m going to see Pose coach JonP tomorrow night so hopefully I will have a remedy quite soon. This will be good because it is really the only thing that is holding me back at the moment.
