The difference was truly astounding to a barefooter/minimalist! Nearly every one of the kids, who were running in everything from street shoes to sneakers, was hitting with a mid-foot or forefoot strike. They were having FUN running. The parents and teachers, most of whom were wearing "running shoes", were doing the heel stomp. I watched with fascination as the kids ran so lightly, like so many deer, just having fun and running with their friends.
This heel stomping style of running, with "running shoes" is TRULY learned behavior, and benefits only the shoe companies (and orthopedists)!
