PF Flyers may have introduced the slogan, but running shoe companies and running stores continue to make bold claims about the benefits their shoes will provide.
Every year, shoe lines update with new technology that brings promises of enhanced performance and reduced injury risk. I used to treat in a physical therapy clinic that was attached to a running store. I analyzed the gait patterns of my post-stroke patients and the running mechanics of high school sprinters and middle age triathletes. I would recommend shoes and buy pairs for my personal training.
