I had my boots fitted with cants under the sole (by a bootfitter in france) I guess to align my knees some years ago.
Now I informed in a shop about fischer vacuum boots , If he was able to add these cants on to the fisherboot. The man told me that
it is not neccessary anymore because the boot is formed to your stance during the process.
Is this right ? It looks only that the cuffs are formed to the shape of your underleg but not the sole of the boot which stays flat.
