I've not looked into the evidence behind the majority of these things personally, but I am taking the lead from very well respected individuals in the industry. I have also tried ALL of these techniques on myself and have recommended them to others and seen many use them on their own. Thus, I've seen that these things do work.
Again, increasing the tissue quality of the anterior/posterior tibialis is not the same as generically lengthening the tissue. If we allow these muscles to exert force more effectively, they will be better able support the arch.

Thank you for the book recommendations
Delvis, you are free to do whatever you like. This stuff will not make you worse, and I've seen it work many times. You could achieve the same results by watching all of Kelly Starrett's videos and reading the authors I have (Eric Cressey, Mike Boyle, Stuart McGill, to name but a few), all I'm doing here is condensing this information into stuff that's relevant to you.
BUT, if you're going to follow any advice I provide you will see the best results if you try to keep to the schedule I suggest.
