I dunno.
I ride Raichle, too. A model older than his. But I absolutely don't feel ANY need EVER to get my heels lifted. Hell, even my bindings are flat-flat-flat. No canting, no nothing.
Boots put you in front by default. Adding to it...I don't know. I think if I was to do that with my boots, I'd end up being all on the toes, on the toeside edge. I would have to compensate then by leaning back. And that can only bring problems: either you can't put your toeside edge in the snow except for laying the turns completely down (not always possible, nor a good idea), or you're completely out of balance.
I learned that one HAS to feel the front side of the boot always. I got a surgery last year 'cos my socks were too rush and made me a wound on my tibia (bone connecting knee & ancle). All the skin went off and the bone got it's share of boot, too. Infection...blahblah...surgery.... And this year again "wounds"
So...I dunno, I don't think it's necessary to lift the heel that way. With binding, maybe? But boots - don't mess with them!
