Replying to Helping people as best I can, as a shop worker

I work at a shop (ERIK'S Bike Board Ski) and I'd definitely say I have a considerable knowledge of skis and boots, but I still want to give my customers better help. Most customers come in saying that they cruise the local Wisconsin hill groomers and are Type I skiers. Generally in that case I direct them to the piste skis and tell them to just go with the lowest price one...cuz idk shit about how different models of piste skis feel. Should I do some more research on them? I figured they would all be pretty sufficient for those kinds of skiers, and the lower-priced ones would be geared towards beginners.

I've sold a bunch of boots and am basically the store boot salesman (NOT a bootfitter cuz I am just a sales associate and can't do shell work). When it comes to selling boots, I'm very wary of giving them a bigger boot for comfort's sake, as long as there are no pressure points or their toes aren't curled up a ton. Maybe I'm being too hardcore? Blister says in their bootfitting guide that it's snobby to assume that everyone wants a snug downsized fit. But imo if you buy a smaller boot (that doesn't give you pressure points or hurt your feet) and use heat molding to expand the liner so it's comfortable, that's much better than upsizing. My belief is that all levels of skiers want a fit that will give them optimal response. No matter what level of skiing you're at, you're probably going to want to progress and try new and more difficult things. If there is slop in your boot, there is delayed response, and if you're trying to learn new things, how are you going to deal with them if your ski isn't even responding predictably? And snug fitting boots should NOT be at all uncomfortable, they should just feel like a firm handshake. How are you going to perform well if your feet are mangled and jammed?

Also I don't really know much about helmet nuances, I was always under the assumption that every good helmet provides adequate protection and the only differences are things like ventilation, amenities, comfort, aesthetics. Same when it comes to goggle shapes.

For everyone who's worked at a shop, how do you give your customers the best possible experience and be more knowledgeable?
