Replying to Boot/Booster Strap Question

I've been riding in some full tilt booters this season and I have liked them a lot so far. No shinbang problems or anything like that, but one thing about them seems a little odd to me. To get them feeling good to ski in, I have to pretty much crank the buckles all the way down. This sometimes puts some strange pressure on my calf. I don't think they're to big for me though because my toes touch the front. Is this normal? Also, would Boosters help this problem? Im about 6'1" 140 pounds so what Booster should I get? Thanks.
