I have a fairly long history of working with high-speed (i.e., slow-motion) video. As a graduate student, I did my dissertation research in a lab that specialized in locomotor and feeding biomechanics of animals, and to do these types of studies, the ability to film at very high frame rates (200 frames/second and up) was […]

I’ve been thinking a lot lately about the relationship between footwear (or lack thereof) and how it affects my running footstrike. Over the past year I’ve been running in everything from full-blown, pronation-control stabilty shoes (Saucony Progrid Guides, Brooks Adrenaline GTS 8) down to Vibram Fivefingers KSO’s, which are about as minimalist as you can […]
