dorsiflexion

This stems from an improperly healed ankle injury causing low dorsiflexion ROM so finding the right combination of exercises is tricky.

While they protect against ulnar deviation, they do not protect against pronation and dorsiflexion.

Stretch your calves, poor dorsiflexion (closing the angle between your shin and the top of your foot) is common and a pain.

A key issue with squat mobility is dorsiflexion, ankle mobility, which I guess you can improve (to a degree) with calf stretches.

Long story short, physio, putting weight on my toes meant my ankle is about 95% back to how it was, just a small limitation in dorsiflexion and plantarflexion.

I have next to no dorsiflexion beyond a straight leg now.

And it looks like I've lost dorsiflexion in the other foot.

I'm 10 degrees away from full dorsiflexion range, and apparently it will still take some time and effort to get to the full range, if at all.

I used an FES ('Functional Electrical Stimulation') device for a while that has a little accelerometer in it to figure out when I intended to take a step, and then stimulate (via conductive pads placed atop the skin) the correct muscles in the lower leg to lift the ankle up (dorsiflexion).
