While adjustable forward lean ultimately benefits you, this adjustment can't really be performed by you alone- you'll need a second person, ideally the boot-fitter. You need to be in the boots, buckled up on a medium-tight tension, the second person loosens the screws in the back, you flex forward to 17° & hold the position, and the second person positions the Power Shift piece and tightens down the screws.
This isn't correct. The liners may look similar from the outside but there are huge differences between a 3D (Memory Fit) liner and a Mimic liner. Both have the same foam layup, but that's where the similarities end. The Mimic liner has a reshapable plastic part in the rear foot, a heat moldable plastic tongue and a heat moldable plastic cuff. When this liner goes into the oven you fully reshape the ankle, heel, instep, shin, and calf to your body and it hardens in place providing a very different fit from the one you get out of the box. Not only does this liner match your body more accurately than an Intuition but it will ski far better too.
Now if you need space taken up, a regular Mimic liner can't really help you. It's not designed to achieve that. What most people are used to doing is cramming a much thicker Intuition liner into the shell but this is hardly a great match that properly works with your body & the shell. The better solution is to get a liner that is actually made for you and for your boot, like a Mimic Professional liner. Then you will have a truly custom liner made for the exact space between your foot and the shell.
