I posted this comment after reading this at Scienceline.com:
I am a lifelong running-boom runner, starting at age 14 in 1977. Back then we ran in Tiger racing flats all the time. Over the last 35 years, the running shoe industry has flourished, inflating soles and prices to where a top technical shoe costs over $100!
For the past 4 years, I have been running 20-50% of my 30-50 miles per week barefoot. It has changed me from a heel striker to midfoot striker, raised a flat arch to a normal arch, negated chronic ankle twisting, allows me to run fast with less intervals, and just feels better than running with shoes. When I do wear shoes, they are minimal cross-country flats. I also go about my daily life as barefoot as possible to support my foot strength for running. It goes against everything the shoe companies ever told us over the last 35 years.
The research has suggested and will continue to conclude that shoes are overrated and over built, often causing more injuries than they are meant to correct. Perhaps this is a self-induced market reset, just like what is happening on Wall Street.
Run fast and light and as barefoot as you can!
