Running Biomechanics & Foot Attire Of The Best Runners In The World

Snippets taken of the running biomechanics (i.e. lower limb) & foot attire (i.e. footwear) of what many regard the best runners in the world - the Kenyans (alongside Ethiopia; yet Kenya tend to have more depth). I have heard & read many times that Kenyans are able to transfer their barefoot running biomechanics into shod (footwear) running biomechanics... this doesn't seem to be always the case. Fortunately the film maker/ camera man had the insight to film quite a few scenes of the documentary focussing on the lower limb biomechanics & subsequent foot attire... thus we are able to assess the variety of lower limb biomechanics of these fast runners.
