Do you still use the 1 to 2 cm shell fit when the (Brannock) arch length is
longer than the overall(toe) length? Looking forward to your thoughts.
I personally take the arch length into consideration on every fit. If the arch length is substantially longer than foot length or the forefoot width is very wide in combination with a longer arch, I will consider sizing boot more to arch length than foot length. Placing the widest part of the foot in the widest part of the shell is sometimes more important than length spacing IMO. Sometimes I will opt to stretch shell to move widest part forward as needed, it depends on the skier and their goals and needs.
got to agree with Bud, rules are meant to be broken or at least bent a little, sometimes you can move the apex of the boot width forward, and other times it is too much to ask.
if the foot volume is high then it will be retained at the back of the boot pretty well without too much of a worry, but each case is individual and requires an individual solution
