I've been running for about 5 years now and almost every year I get problems on the medial side of my shins. If I keep running, eventually the soft tissue even swells up enough to be palpable and painful.
I know I have very poor ankle stability, when I try ice skating it's so bad that the medial side of my shoes even touches the ice. I also have quite some pronation, all the way through my roll off, that get's worse when I start running faster. Together my weak ankles and some overweight, this is resulting in some recurring shin problems.
Here's some nice images from under my feet when walking
I started running again 2 months ago and focused on building it up slowly and not running too much (max 3 x 5km per week). I hoped this would prevent it from recurring and built up sufficient strength, but this morning I started feeling one of my shins again.
So now I'm looking for exercises I can do (at home) to strengthen my ankles!
It's also fine if its whole leg exercises, but my main focus is on increasing my ankle strength.
