I wouldn't know about the heel being raised by them too much. I've never tried changing to aftermarket insoles inside of the liners. I've used them in every other shoe though and the toe side always wore down before the heel side.
The ones I linked to are the thickest ones they sell; 5.5mm, with a really high arch. They are specifically recommended for use in snowboard boots, so I'll give 'em a shot.
