Oh, you're welcome @serowa. If he can buy "Older Yet Faster", Heidi has a whole chapter on rehab'ing from running injuries and using the wrong shoes. There's a whole section dedicated to plantar fasciitis. And while I haven't had plantar issues for years (and therefore don't need to follow the advice in that section - I have other issues that have taken me to this book) I have every reason to trust their suggestions as everything they're saying in this book is in alignment with everything else (decent) written about the biomechanics of the foot and the rest of the human body. I'll write more on the book when I've done their program, but for now, I'm just reading and loving it.
Hmmm, CBD oil, hey? You're the second person to tell me about this in the last week or so. Interesting. Just for pain relief?
