As I understand it, there are 3 main types of canting designed to get the ski flat:
-wedges under the binding
Actually, I guess there's cuff canting as well but I wasn't sure whether that was designed to centre/off centre the leg in the boot or make the ski flat.
A custom footbed should make pressure even across the foot and help flatten the ski but if you need canting after that, isn't the in boot or binding option the easiest to do? If you add the canting afterwards, doesn;t this change how pressure is applied across the foot?
