And what about # 260?
Things are certainly different for this chap compared to # 172. His take off from his right foot looks pretty good. His left foot looks like it is going to cross over with some medial knee fall as it descends to hit the ground. Just before it hits the ground, it should be supinated in some degree of dorsiflexion (he is sprinting, so we expect some plantar flexion because he is sprinting), inversion and adduction. His pelvis is nice and level. His arm swing looks pretty good with only a slight cross over on the right as it is coming through. With form this good, no wonder he is out front!
