I'm among those few that don't like the the new VF-19 gerwalk mode.
I'm at my office so I don't have my VF-19 nor the YF-19 so I'm posting this pic from the net:
The leg bends "back" at a lower angle due to more forward/back movement at the ankles. It's a much more extreme and aggressive stance, better than the new VF-19 can reach.
Fighter and battroid mode of the new 1/60 VF-19 are top notch but gerwalk mode is a step back due to the poor back and forward movement at the ankles. I wish Yamato goes back to ratcheted ankles for the possible YF-19 ver 3 since it is my favorite from the 19 series.
