Replying to How to boot fit in a ski shop?

Hey guys, I have been working in an outdoors store for a few years now in NZ, going into my third winter season where we sell skis/snowboards and boots etc. all the usual ski store stuff, I’ve been wanting to get into ski boot fitting but have never really fully committed to it, last season I did a bit with snowboard boots but I understand ski boots are a fair bit more technical and not something you want to get wrong. I’m gonna get one of the guys already doing it to start teaching me some stuff now but are there any bootfitters out there with some good tips?
