@MarcoBalletta @bubbleball @KATVR It looks like the design changed at some point and they made the platform you walk on a lot less curved, the actual floorspace it takes up is smaller too as the platform is also smaller. The rear bars at the side are just angled not bent near the bottom either and if we compare vids of how people walk on each version we can see that the actual motion of walking has drastically changed, for worse, because of it and your pic @MarcoBalletta shows us yours is the new one

Newer, crappier version:-
Now its far too similar to using say Natural Locomotion app with vive foot trackers or Pocket Strafe app for 2 phones in your pockets and just walking in one place/no actual striding forward.
