No, I am not planning to run naked for the next 90 days...
Something has to budge. I refuse to acknowledge that the wear and tear of 105 ultramarathons is why my knees hurt. It has to be my shoes. It looks like the one extreme of running barefoot has moved far enough toward the other extreme of running in climbing boots for me to try something a bit different.
"Natural running" is the term that is gaining ground on "barefoot running". This mostly because "natural running" accepts that shoes are not our enemies.
