In reply to andyd1970:
My Plantar Fasciitis was a result of injury/overuse, lack of time to heal and then going chronic i.e. just there all the time. I went to the Physio after it eventually stopped me running.
Physio told me that my problem was that after inflaming it simply walking on it every day was sufficient to keep it in a chronically inflamed state. I couldn't take time off my feet to allow it to heal - kids/work etc. Advised me to strap it instead. Strapping works by taking the strain/load off the inflamed band as you walk around, that in turn slowly reduces the inflammation, then some healing can get done.
Once strapped properly ... I got zero pain almost immediately while walking.
Strapped it up with something that looked at lot like this.

Strapped it up using this stuff:

The really wide stuff is good for covering ball of the foot and saves time.
(Exactly the same stuff they sell you in the climbing gym for your fingers, but in white and fraction of the cost of the stuff branded for climbing. hint hint. )
Strapped it fully every day for a month except when sleeping before gradually reducing it. Took me ~3 months before I could run again. I went with theory that if I couldn't run without strapping it ... then probably back running again too soon and I had to wait longer/keep strapping.
Never went with insoles presumably because my PF was a result of injury/overuse - not because of the shape of my feet or the shape of the shoes I was running in.
Come back and tell us what fixed it for you.
