Kinda, sorta moldable.
DO NOT bake them like an Intuition!
That liner has a layer of heat moldable EVA foam that is glued inside. You can gently heat the inside of the liner using the mild heat stacks that some of the boot manufacturers provide.
The EVA foam will adapt to your foot in the first few days of skiing without heating them.
If you put that liner into an oven for too long some of the glues used to hold the thing together will come apart. Also the outer cuff of the liner is made out of low grade thermo plastic that will melt at Intuition liner heat times and temps.
