Just wanted to make it perfectly clear that even though I am wearing Tarahumara huarache sandals these days, I am still able to barefoot in extreme situations. It is all about being light on your feet and focused.
As a matter of fact, until you are able to barefoot on hardcore trails, you will not have mastered the technique required to run in low profile, minimal shoes or sandals off-road, in my humble opinion.
PS. There is some sound at the very end of the video...for effect.
