In reply to kylo-342:
Personally I found that when my PF was at its worst the degree of cushioning wasn't important: what was important was having a shoe that didn't allow a walking gait and foot position that aggravated the PF. For a while I could only contemplate fully supportive walking boots with green super feet insoles (having tried gel cushioned insoles and all sorts of combinations of footwear). A regular runner friend on the other hand found gel inserts in trainers to be ideal for him.
Now I wear somewhat pricey Merrel approach shoes (which fit me and suit my particular pronation etc.) all the time (work and play) and - touch wood - no recurrence of PF.
So along with regular foot stretches it really was a case of what worked best for me and it may well be a similar level of experimentation for you.
