Caucasian_AsianA boot fitter fits boots. A boot salesman is not a boot fitter.
if you're selling ski boots you should know how to fit them its as simple as that. my first year working at a shop I spent the entire summer before the shop opened getting trained on how to fit and work on boots properly.
and to OP it all depends on the persons foot what boot they like that fits them the best, some people just get custom footbeds while some people need some fine tuning done to the actual shell of the boot ie shaving down the boot board a little punching out a pressure point ect.
