Renowned scientists like Dr Nicholas Pose-anov and Christopher McVibram (born to run) have proven beyond any doubt that it is impossible to run efficiently with a heel-strike, and that this will undoubtedly lead to injuries and slow times, yet Meb has been heel-striking forever and is unbreakable and a multiple marathon major champion, not to mention silver medalist and OT winner. How is this possible? Would Meb be running under 2:00 with proper form, including soft-landing, gravity-using fore-foot strikes?? One would imagine so.
What a shame Meb was not fixed a long time ago by such experts. Yes, a stinking shame.
