Study design: 927 male and female runners from 18 to 65, prospectively evaluated as under- or over-pronator or neutral, given light-weight NON-motion-controlling shoes, and left alone to run as they please for a year.
From 5k Fashionista.
The lead author concluded that runners are better off paying attention to "things like body mass, training, behavior, age and previous injury in order to prevent running-related injuries." Admittedly, I'm posting this because what I don't want to hear from the super-paleo "all shoes are bad" crowd is that this study supports their conclusion; it just leans us further toward "follow your natural stride type". And to that end, some of us, your blogger included, are obligate 21st century runners whose build, foot shape and size, stride length, and running habits requires us to wear a well-cushioned (if not motion-controlling) shoe. And I've never had a use injury in 22 years of running with no warm-ups, or stretching, or proper build-ups to big events. And this paper is telling us all that our natural stride/strike is a-okay!
