It’s a horrible thing.
Rolling a small frozen water bottle on your foot gives relief.
I had insoles made with helped loads when it was awful and I also have various over the counter insoles. I use a elastic sort of half sock the supports the instep which I use sometimes.
Physio helps as does lasering the area.
Fling out shoes that make it worse.
It was years before I could walk on hard floors without shoes.
