We don't have AB on most of our jets.

Have you never come across a low experience pilot, who didn't have their heels on the floor, and who applied the brakes unintentionally during the rudder control check during taxy?
Nope. FOs don't do the rudder checks here!

If the RTO is performed below the autobrake threshold speed, then there is plenty of runway ahead and time to sort out your feet transition from floor to brakes.
Agree. But the issue is a V1 cut/fire.

Punkalouver's post further makes my point about moving feet up during a max-brake reject. Practically, it can't be done.

The general rule is that if you have a fire or a large loud bang before V1 you stop. That means max braking. The issue is not what happens 80kts (or even up to V1-10), surely that's obvious?
