Hirscher's inside foot rarely moves forward in the critical part of the arc. A great aid for keeping all the pressure focused over the center of the outside ski.
Compare the difference between the two skiers here. Ted is on his inside ski and also in the next frame less balanced than Hirscher. Obviously this is one turn out of 50, but this pattern was consistent and undeniable as the difference between the two throughout the course.
Ted Ligety compared to Pinturault. Ted more leaned inside and hips further back, as he does in slalom. Ted already too extended for this part of the arc.
With Pinturault you see similar compactness as Hirscher and the hips more forward and more lined up with the outside skis boot.
