Various articles (including the excellent set-up ones here) mention aligning your high-backs parallel with the edge (or as close to as possible) to aid heel-side control.

I have new Flow NXT-AT's and the high-back can be adjusted, however it also adjusts the heel-cup, which is probably undesirable.

Anyone with Flows know?

thanx in advance

Can you take any photos? I'm trying to picture it...

I don't think rotating the heel cup should make any difference. Is it all connected as one?

Yes, it is all connected. Looking at it I am thinking that the adjustment is only for adjusting heel-toe placement, not for rotation. The screw just under the back strap on each side controls how far forward or backward the heel cup and high-back are.

Yeah the screw for highback rotation is highlighted here:



If I remember correctly, that screw will allow you to adjust the heel cup and the rotation of the highback. Definitely use it to rotate your highbacks to parallel with the heel edge.
