A basic version of this tutorial was first published in 2003 when I originally observed that many stubborn cases of plantar fasciitis could be cured by “power icing,” and I wanted to get that idea out into the world. The tutorial underwent a major upgrade in July of 2006, becoming what I still believe to be the best available single source of information on the subject. Numerous minor improvements have been made since then, and this record of changes was started on August 26, 2007. A particularly large number of improvements were made in the fall of 2012 while preparing to record the audiobook version.
A major feature of my tutorials is that I actively update them as new science and information becomes available. Unlike regular books, and even ebooks — which can be obsolete by the time they are published, and can go years between editions — this tutorial is updated at least once every three months and often much more. I also log updates, making it easy for readers to see what’s changed. This tutorial has gotten 53 major and minor updates worth logging since I started logging carefully in late 2009, and countless more minor tweaks and touch-ups.
Upgraded (Apr 1 '14, section #3.3) — Much more information about the (minor) significance of bone spurs. They may not matter a lot, but it’s good, useful, evidence-based context. See section #3.3, Using other diagnostic technologies.
Major update (Jan 1 '14) — The first complete professional editing of this book has now been completed. Although the difference will not be obvious to most readers, several hundred improvements and corrections were made, and it is definitely a smoother read.
Minor update (Dec 11 '13, section #2.3) — Added a fun science item about the amazing ankle mobility of the Twa people of Africa. See section #2.3, Probably my calves are too tight!
New recommendation (Jul 11 '13, section #3.3) — Now recommending a specific type of MRI to scan for bone swelling. Thanks to reader R Russell for the suggestion. See section #3.3, Using other diagnostic technologies.

New section (Oct 17 '12, section #4.1) — New standard section I’m introducing to most of the tutorials to “manage expectations.” Too many readers assume there’s going to be a specific miracle treatment plan. See section #4.1, So what’s the plan?
Rewritten (Oct 15 '12, section #4.8) — Completely revised to reflect new science and new understanding of the interaction of ice with “inflammation.” See section #4.8, Icing: more is better?

Edited (Sep 18 '12, section #2.1) — Longer and clearer than before. In particular, I came up with a much better way of explaining the fragility of “bony” spurs. See section #2.1, Getting to the root of plantar fasciitis: could it be bone spurs?
Science update (Jul 4 '12, section #4.19) — Added good new evidence that customization of orthotics isn’t very accurate. See section #4.19, Arch support, heel cups and orthotics.
New section (May 11 '12, section #2.8) — Inspired by something surprising that I learned writing the new surgery section, this is a brief description of another major possible explanation for persistent symptoms. See section #2.8, Plantar fasciitis in the bone?
New section (May 10 '12, section #4.4) — Substantive new section of about 1400 words, with several footnotes and new references. See section #4.4, Surgical options for plantar fasciitis: so many!

Major update (Jun 21 '11) — Major improvements to the table of contents, and the display of information about updates like this one. Sections now have numbers for easier reference and bookmarking. The structure of the document has really been cleaned up in general, making it significantly easier for me to update the tutorial — which will translate into more good content for readers. Care for more detail? Really? Here’s the full announcement.
New section (Mar 20 '11, section #4.20) — Finally, long overdue, a new section on this topic (for all the running injury tutorials, in fact). See section #4.20, Should you run naked? On faddish running styles and running shoes (or the lack thereof).
Important new info (Feb 8 '11) — Where’s the fire? Recently I published a major new article about repetitive strain injuries (like plantar fasciitis), in which I explain that these injuries are rarely actually inflamed. Instead of being “on fire,” excessively stressed tissues tend to break down without inflammation — a kind of rot. This significant fact of biology is not yet given proper attention in this tutorial, and it should be. I learned the science of this myself only just recently, and it is going to take me a while to revise all of the tutorials and articles that are affected by it. Meanwhile the new RSI article is available, free to all, and I have also mentioned and linked to it where necessary throughout all tutorials. For the full scoop on inflammation and repetitive strain injuries, see: Repetitive Strain Injuries Tutorial: Five surprising and important facts about repetitive strain injuries like carpal tunnel syndrome, tendinitis, or iliotibial band syndrome.
Minor update (Jan 18 '11, section #4.19) — Added a reference to a large, interesting study that showed that custom orthotics failed to reduce injury rates in marines. See section #4.19, Arch support, heel cups and orthotics.
Improved (Sep 30 '10, section #2) — Beefed up with better explanations and science about how plantar fasciitis involves more “degeneration” of your foot than inflammation. See section #2, Nature of the Beast: What is plantar fasciitis?
New cover (Aug 6 '10) — At last! This e-book finally has a “cover.”
Expanded (Jul 16 '10, section #4.5) — Added a substantial chunk of content about a promising experimental treatment protocol. Unproven but interesting. See section #4.5, Steroid injections are promising but problematic.
Minor Update (Dec 30 '09, section #4.25) — Some new comments on Graston Technique in response to a reader’s questions. See section #4.25, Don’t bother with ….
Minor update (Dec 30 '09, section #4.10) — Added an answer to a reader question, “Are soft night splints good enough?” See section #4.10, Know your stretches.
New section (Dec 30 '09, section #4.5) — No notes. Just a new section. See section #4.5, Steroid injections are promising but problematic.
