just saying get fitted at a bootfitter definitely isn't good enough.
do some research about ski shops in your area, find out about their bootfitting experience and don't come to the store with a set boot in mind that you want.
make sure you don't just find any bootfitter (most stores will say they do custom boot fitting), find the BEST, most experienced bootfitter available in your area! If that means driving an extra hour, do it, your feet will thank you later!
