The safest & best (for your protection) way to get a helmet that fits properly is unarguably to buy a helmet that closely fits your head shape & then get the appropriately sized/thickness liner installed that means it firmly & evenly holds on to your head everywhere it touches!! If your full face helmet doesn't firmly hold onto your head all over & your cheekbones then it's TOO BIG & it isn't as safe or protective as it could be!! A new helmet SHOULD be tight & even borderline uncomfortable all over your head, and it SHOULD take a few days of wearing it to 'wear it into shape' so there's no really painful spots as opposed to tight spots - if you choose one that is comfy from the first fitting, then IT's TOO LOOSE & it won't protect your head the way it should if the worst happens!! It should be obvious to those looking on when you've just taken your new helmet off from the 'pressure flush' it leaves on your forehead & cheeks/face - if you choose a helmet that doesn't muss your 'do taking it off then it's not only likely that it's not gonna save your head if you have a serious prang, it will quite likely snap your neck or fly right off so you can crack your head like an egg hitting the pavement at speed!! Generally speaking, good quality Tight helmets are the best helmets for protecting you, BUT, all that said, smallish & painful pressure spots are not a good thing! :shocked:
Most good quality helmets DO have a variety of sizes &/or shapes aimed at fitting most of the different shaped heads there are around the place, and most have a variety of liner thicknesses to allow you to 'fine-tune' your perfect fit, even if the outlet you are dealing with doesn't stock all those shapes, sizes, or liners. So you could try tracking down the best liner for you.... Revzilla is really good at doing that! Buuut, failing that, using a spoon or similar to compress the HD polystyrene looking stuff under the liner can work as a last resort (no flaming intended Kaos, it works!) altho if you've already tried that with the liner in place, you might need to either remove the liner entirely (most are clip in these days) or carefully lift/peel the liner off the white polystyrene looking stuff & then with a SHARP knife, very carefully & little by little shave it down to suit the bumps & bulges of your head!! If you take too much off, you've stuffed it, cos there's NO SAFE way of adding replacement material once that polystyrene stuff has gone!! In that case, adding a thin layer of foam or an even thicker liner can make it more comfy, but it will also reduce/compromise the protective ability of the helmet, and really, why are you wearing a helmet in the first place?? :dontknow:
So Newbert, I'm not having a go here, but seriously asking, is it really a 'pressure point' that's causing potentially unbearable pain, or is it the only tight spot on an otherwise OK fitting helmet, or is it just a poorly fitting helmet?? Only you can really answer that, but from reading your posts, first the cheekbones, & now this.... :dontknow:
