I think for most people there is no question that in his turn, a hero may spend movement points only in step 3 (Perform actions). Movement points gained at the start of the turn ( Elven Boots , Okaluk and Rakash , etc.) cannot be spent in the start of turn step.
However, does somebody have an official or unofficial answer from FFG on this? I was pretty sure I had one, but cannot find it anymore.
