I was intrigued by these shots of me running. It's one thing to try and run a certain way, and a completely different thing to then see pictures of that form in action.
Two things here: first is the clear preparation of the foot for an outer forefoot strike (just behind the pinky toe; second is the way in which one foot is right in front of the other. For me, it creates a straight line about an inch or two in from the inside edge of my feet. When I had to wear snowshoes, it felt really strange and hard to have to walk with a wider stance.
Shoe companies would have us believe we need support and protection; however, this shot clearly shows my left foot's arch (AKA windlass mechanism), at full load. That kind of compression is supposed to happen (it absorbs shock of landing, and returns close to 20% of that energy back to your next step). Any arch support prevents this natural mechanism from functioning at all. Arch support does nothing but weaken the foot, send unnecessary shock up through the leg, and make the whole body work harder to propel itself forward.
-- Every 22 seconds, someone in America receives a brain injury.
-- That totals 1.4 million people in America receiving a brain injury every year.
-- Of these, 50,000 die; 235,000 are hospitalized, and 1.1 million are treated and released from an emergency department. (stats are only known for those who seek help in an ER) (BIAUSA.org)
-- The annual incidence of TBI alone is higher (perhaps up to 6x) than that of breast cancer, multiple sclerosis, spinal cord injury and HIV/AIDS combined. (Reference)
-- Every brain injury causes permanent damage, even mild concussions. The good news: the brain is resilient, and often creates new pathways, making it seem like no permanent damage occurred. The bad news: neurological "detours" use more brain energy and people can experience the world as "being harder" without realizing why.
-- Having one concussion increases the chances of having another. This snow-ball effect continues to increase with each concussion.
-- Damage from subsequent concussions is cumulative -- so multiple mild concussions can result in significant impairment, even if the first 6 or 7 did not seem to effect you.
-- Brain injury is often called the "Silent Epidemic" because brain injured people often look "normal" despite experiencing life-altering effects.
