Replying to Molding my Full tilts???

Hi guys!

About a year ago I really started investing in skiing as a hobby, and i got myself a pair of Full tilt descendant 6's! Although they looked cool and i had heard that Full tilts are great boots, they might not have been the best option for my feet. Although I have used them (quite a lot) for one whole season, I have to unbuckle them every time I get on the lift; if not, my feet hurt to much... Could it help to mold the "case" or the liner in any way, if so, what type of molding should i use?

Thanks in advance! Any response is greatly appreciated :)

Best regards from a dude with uncofortable feet.
