You are probably not going to listen to this, but I was dealing with this for 3 years.
I did everything. Legit everything. Spent shit ton of money and nothing worked, not even a little. Could barely reach the store.
If you've tried the conventional shit; shoes, soles, shockwave, physio and it doesn't work then read below.
Isometric pushes, MAXIMUM force for >20 seconds. Example:
Place your toes in 90 degrees upwards towards a wall and PUSH as hard as humanly possible towards the wall. You can do the same thing with a hamstring/calf stretch but push towards the ground instead.
If you understand the gist, you should be able to think of other similar pushes.
Lastly, stand on 1 foot for as long as you can. DO NOT hold on to something. You need to keep balance. This may or may not aggrevate your problem, it is expected.
Do these and rest 2 days. Repeat.
Problem will improve in 2 weeks, gone in 6. Thank me later.
