Replying to Full Tilts not snug around leg

So I've had a pair of drop kicks with intuition liners for over a year now. The boot is really snug around my foot but the intuition liner at the top of the boot just doesn't hug around my leg. Like if i lean forward then my calfs wont be touching the back of the liner and vice versa. Its really weird and it happens towards the end of the day after riding a lot. Tightening the boot doesnt actually seem to do much either. Any suggestions? anyone else experienced this? maybe time for a new boot or shall i bus out some tape and force the liner to be tight to the leg.
