I struggled with a posterior tib issue for like a year. I worked on gait, especially engaging my glutes. I slowed down my pace, too. I use the Mizuno wave inspire which is, I believe, a stability shoe, with the old style green Super Feet support inserts. I have small ankles and a bony foot and the shoe and it’s predecessors have worked for me.
Thanks for this post. It reminded me to do my hip bridges!
