Much like with IT Band Syndrome, for me personally I found that the most useful approach was manually stretching it out, in this case via one of those socks at night. But even during the day I could do things where I would sit in a position that would stretch out the bottom of the foot. Wrapping the arch was a temporary help, same with rolling over a ball and strength exercises.
The approach of manually forcing the extension of the fascia seems a bit medieval but makes sense from a biomechanical standpoint. However, I will say it doesn’t work for everyone, especially when the condition is pretty severe.
