Could someone explain how the whole binding sliding thing works. Are you even supposed to slide bindings forward/back. (The little metal ledge you push up under the heel and let them slide ~1cm at a time). I was always under the perception you can just slide the binding to fit you boot until my shop made me remount for like a 5mm difference a year ago.
Is there a big deal if you boot is a whole 2mm off from the binding, does it just effect when the binding releases/ the "energy transfer" between foot boot & binding?
If the ability to move bindings up/down is usable, when can it be applied? By how much do bindings move at each "step."
