Replying to Boot problemo

Aight NS pleeeease help me out-here is my situation. As of now my boot set up is as follows: 2009 SPK Kreation (yellow and black) shells with regular power strap and Full Tilt intuition custom heat molded liners. Now the tech at the ski shop and others I have talked to had this set up and it worked out fine. My problem is: I have NEVER had shin bang in my life with my SPKs and the regular liners. This year, I put in the CUSTOM intutions and 5-6 days into the season, the shin bang is here. I am not quite sure if it is shin bang or just bruising around the top of my boot, but it hurts a lot. Today, as I tried to jurryrig my boots to feeling nice, I put in my old stinky factory SPK liners and they felt great on my shins, but they are a smidge too small on my feet. SOO, has anybody else experienced this phenomena? Should I search for some slightly larger liners that will fit in my 27.5 boot, buy some booster straps, tough it out, or somehow come up with 300-400 for new boots all together? Please help me here ns I am in dire straits, thanks!!!
