I don't think that's normal

some cheekpads have peelable layers to reduce thickness
some helmets can be accessorize with thinner cheekpads

another reason could be the helmet is to low, check that you have about 1 finger width of space between eyebrow to top of visor window, by pushing the chin bar upwards to roll the helmet back, see if this improves the comfort

oh, it's a touring helmet? with spectacle grooves at the side?
maybe check online for cheekpad photos, after removing the fabric
some have peelable sponge to reduce thickness




if not, source for thinner Shoei cheekpads
