I just set up 3 pairs of flow's.
You do not need the power strap as tight as you would in a 2 strap boot. My boots and my kids, the 2 others, are just snug. Make sure the strap is even on all sides of the boot not pulled more to one side or the other.
I hope this helps
Sidenote: My boy bought the flite 2's I returned them for the M9's
