I feel your pain, as I have had a bad bout of PF which took a long time to clear up.
Having read a lot around the seemingly contradictory advice, I have a model which makes sense to me and integrates the contradictory advice, well it worked for me. The differences are for me explained by the difference between things which might help relieve an acute attack and things which in the very long term will make things better.
Heel raises and calf stretches straddle both these and help in any case.
After lots and lots of exercises, https://nutritiousmovement.com/feet-and-shoes/ is a good place to start, your feet will be strong, your calf muscles more pliable and all will be well in your world, and barefoot will indeed be the way forward. Especially first thing in the morning, some gentle stretches before you put your feet to the floor (after then have been relaxed all night) helped me a lot.
In the short term, however, some cushioning in your shoes, even a slight heel can allow your shortened calf muscles some relief. They are temporary measures, which mask the real problem, so the key is to find the balance between short and long term measures that works for you.
Another complicating factor is that very, very few health care professionals have any truck with the barefoot approach. Why would they, when it would ultimately put them all out of business? There are a few, but they are few and far between. It is not easy to ignore what they suggest about steroid injections and deadening nerves and keep on with your calf stretches.
All the best, I hope you find what you need...
