I actually go the DC Status this year, too. My first BOA boot. I've been experiencing the same thing as you. I keep them real loose until I'm about to get on the first lift. Then I snug them up. After the 1st run I'll tighten them again. I've used them 7x so far this season, and end up tightening them up again another couple times during the day. They're really stiff boots, so they're barely broken in at this point.
