What size is your foot and what size sock are you using.
If you getting your sock all bundled up as you put your foot into your boot. Almost sounds like your socks are to big. Have you thought of sizing down your socks
I buy Med as I'm on the bubble of Lrg/Med and the Med stay more snug and I just like the fit better of Med than a looser fitting large.
Just a thought
