Plantar Fasciitis Arch Support
Why are you supporting something that doesn't need supporting! The plantar fascia is a thick fibrous band that's very similar to a bow and arrow. The plantar fascia is the string of the bow. It ties and holds tight one end of the arc to the other. To use an arch support inside your shoes is like saying that we need to have an arc support on the bow to make it function better.
The problem with orthotics and arch supports that are used to treat flat feet, fallen arches, and painful feet is that they don't support the arch of the foot where it actually needs to be supported. To properly support any arch, such as a bridge over water, either end of the open space should be supported. In the case of the foot, the heel and balls of your foot should be supported, but not the space in-between the ends of the arch.
