The source of all of our intelligence, or bodily wisdom, and what does it mean to be human? To walk. To be bipeds.
Therefore, the most important shoes are the ones that motivate you to walk and move, and cause as little pain as humanly possible. Typically this means the more minimalist, the more barefoot, the least amount of padding. Zero drop.
Water shoes tend to be good. I’m also interested in the minimalist sandals from Xero.
