ok, i guess i probably wasnt very clear in my initial post. obviously i'd mold the liners with the footbeds in, that's how you'd work with any heat moldable liner. my concern is that the bottom of the liner isn't a few millimeters thick and flat like regular liners, it's also heat moldable. so does the mold of the bottom of your foot in the liner provide enough support while skiing? i pronate pretty badly and have very flexible feet/ankles, so i usually end up getting pressure on my inner ankle if i don't have footbeds, but i didn't notice that with the intuition liners. how are you posting your footbeds? when you say custom molded, i'm assuming you mean the Conformable ones, or something similar? posting seems like it would just take up more space in the boot due to the thickness of the bottom of the liner.
fyi, i've been fitting boots for a good long while, this is just my first real experience working with intuition liners and the best way to tweak them; my shop didn't carry them in the past.
