Nothing there that has not been said numerous times before.
Bandwagon jumping me thinks.
I disagree with this for instance:
This could be why the rate of ankle sprains and knee injuries for athletes in various sports has increased rather than decreased, despite the abundant options in athletic shoes. A September 2010 article by Laura Miler in "Becker's National Orthopedic and Spine Review" noted that "sports-related foot and ankle injuries are increasing among athletes," In fact, several studies have shown that those who wear high-priced, high-performance athletic shoes are actually more likely to suffer an injury.
Its not solely down to the use of sports shoes/trainers. I feel its more down to the fact that children growing up a decade after me & you were plonked in unsuitable footwear (trainers) far sooner than they should have been. Have not spent as much time as we did running around barefoot & now we are seeing the price of weak feet because they were not allowed to develop proprioceptive feedback & strength in those areas.
He also says that forces of up to 3 times body weight are sent up the body because of heel strikes.
Its well known that when running the impact forces anyway are 2.5 times body irrespective of how the foot lands in regular runners.
Again I thinks its bandwagon jumping.
There's nothing new there.
