Lani.....you're most welcome.
the plantar fascitis happens for the exact same reason, compromised foot strike. With a normal level of demand, you may have just experienced that compromise as feet that were sore at the end of the day. But as a runner, your margin for postural error was much less. The more demand we present to our bodies, the more postural compromise's impact on joint function becomes amplified.
You'll dig the book. In the meantime, here's a
short video from our VP of Therapy Protocol talking about the linkages between postural integrity, running, and doing so pain free. It's focused on back pain, but the principles apply to any kind of pain. Enjoy.
