I've discovered what I think is the most helpful book I've read about how to prepare my feet and body for my thru-hike and beyond. The title may not sound applicable, but the information in here is fabulously helpful. I say this because of the barefoot shoe discussion, which he talks about extensively among many other subjects like building endurance, what to eat and when for endurance events, muscle imbalances, breathing, music therapy for athletes, etc, etc.

Of course, he says that if you go minimalist you have to rebuild those leg and foot muscles you've lost by wearing supported shoes. I'm working on that now, with nine weeks until I leave on my thru.
