I woke up this morning with a pain on the bottom of my foot, basically the arch. It was pretty painful, but loosened up. I ended up playing on it, and it felt fine, but after I was done, it was painful again. Is this the start of PF? I already wear custom orthotics, so I am confused why I developed it. Most of the posts on here recommend getting them. I have been wearing Prince T22's over the last 2 years. Any advice is greatly appreciated.
