Default The feet - rotate or not

When doing the kick what is the benefit of rotating the feet inline with body rotation (ala Terry) vs straight vertical up and down (ala Shinji)?

Thanks

There is no/less benefit of kicking sideways.
Feet kick in line with hips, and Shinji rotates shoulders more than hips so he kicks more down than Terry.
His hips dont stay totally flat se he also kicks partly sideways.
Mainly sprinters rotate hips very little, with more shoulder roll relative to hips.
Kicking down is more efficient to lift the rear than kicking sideways. Kicking totally sideways gives a horizontal force vector, so zero lift, dropping legs and hips.

I would argue this slightly differently. Terry doesn't need to kick down to support his hips because his balance is sufficient to keep his hips up. the purpose of the kick is not to keep the hips up but rather to initiate rotation. in this sense a sideways kick can also suffice. That said, Terry's kick seems to be much less pronounced than Shinji's, more as if he is only using it to stabilize rather than rotate. Not sure of this, but my recollection is that there may be a slight asymmetry in Terry's kick, left to right, as well.

Just took a second look. It seems that on one side Terry kicks with both legs. One goes up and breaks the surface at the same time as the other is going down. On the other side, the opposing leg moves much less when the other side kicks.

Terry pulls first, kicks afterwards, so he doesnt initiate the rotation with his kick, he supports it.

Front end pullers often have the rotational kick at the start of the catch, back end pushers at the finish.
Terry is a back end pusher.
There is quite a big variation in kick timing relative to body roll, relative armpositions, arm entry. I have stopped labeling them as good or bad in a certain range. People can have widely different accents in their stroke, connect in some way with the kick, even at olympic level.

If you attend any TI workshop, you will find that they do not advise to rotate too much. If you rotate as much as TI coaches advise in their workshops, you will find that your feet /legs mostly remains horizontal. This type of question that you asked, I think, arises only when you rotate too much. Legs move like a log.
