Support Bob Ewing in his D.C. Barefoot Marine Corp Marathon Run

Bob Ewing is once again running the Marine Corps Marathon this year, but unlike his previous MCM last year which he ran in Five Fingers and raised money for St. Judes, this year’s marathon is being run in honor of Bob’s mother, who is fighting cancer, an…

Digging into Daniel Lieberman’s Barefoot Running Research

Do modern running shoes effectively force runners to heel strike? Here we dig into Daniel Lieberman’s barefoot running research, and also poll the Vibram Five Fingers community regarding how to walk or run in shoes versus Vibrams.

Results of Daniel Lieberman Barefoot Running Research

Screencaps from the Nature video, this image shows that initial impact running with a heel-strike registers at around 1.81 x body weight compared to .34 x body weight initial impact running with a forefoot strike. Interestingly, peak bodyweight impact on each curve registers higher with a forefoot strike — around 2.60 x bodyweight running with a forefoot strike compared to 2.30 x body weight with a heel-strike. Note in both running styles here, impact is measured with barefeet.
