What kind of inserts? For my PF I got arch supports from Pro Foot and they worked wonders. Heel pads are useless, you have to get the tendon stretched out again. Of course until you can get the inflammation down in the first place I'm not sure anything helps. My sister got one of those braces that pulls the ball of your foot toward your shin but when she loaned it to me I found it didn't pull mine forward enough. You do the towel around the ball of your foot pull, too don't you? That one is for before getting out of bed in the morning.
Thanks for that advice Olive. It has been gettingprogressively worse. I even succumbed and got shoe inserts. Did not help yet!
