Mark Sisson (@theprimalkitchen) ran for decades in cushioned shoes and paid for it with a hip replacement he believes was preventable.
Seven Gs of force hit your hip with every step in cushioned shoes, versus one or two when your feet can feel the ground. That number reframed everything I thought I knew about footwear.
Mark is the forefather of the primal movement, founder of Primal Kitchen and Peluva, and he’s spent decades studying what keeps a body moving into its 70s and beyond.
Wide-toebox shoes alone will not undo a lifetime of damage. Mark explains why toe articulation is the piece almost everyone misses, and why the big toe, the most important joint in the foot, shows its lost function in your knees, hips, and glutes.
Also covered: Failure Magazine, a $1.5M TV flop, the pivot that became Mark’s Daily Apple, cold plunges, keto, TRT, biohacking, and why chasing a top-2% VO2 max might cost you your life.
If your feet hurt, your knees hurt, or you want to still be walking at 90, this one’s worth listening to.
