Plantar Fasciitis is a new affliction over the last few months. Yes, kind of a pain. Recently I have tried using all the above aids & it has definitely helped — along with decent arch supports in my walking shoes.
Just wanted to share this with you in case you too were having issues. These aids are cheap enough. So worth trying. The secret, I have found, is to really lift up the arch.
Best of luck. Let me know how you fare.
