All I can tell you about these is that if you've actually got plantar fasciitis you can spend an almost limitless amount of money on them and they may seem an improvement but they won't actually help. This I know for certain.
Instead, see a podiatrist and get custom insoles made for your feet and then learn to walk again. It's a big improvement.

I finally saw one after far too much suffering.
Maybe don't be a me.
I had such orthopedic inlay soles a long time ago. In Germany they are a thing and covered by the medical insurance.
Worked for me well.
However, my first ideas to tackle posture issues would be:
* go barefoot as much as you can
* use minimalist/barefoot shoes
* do postural education. E.g. this yt channel is really great:
