Pressure points are never a good sign with helmets, it can often lead to headaches and or migraines over time.
We do not advise removing or customising the EPS foam in the helmet and thus make the warranty void. More than likely it is the new helmet liner that has created these pressure points as it is not worn in, a tip for this is to place a comfort pad on the crown of the head inside the helmet. This will allow the helmet to size a millimetre higher on the head and possibly give relief to the pressure point.
If this tip did not work, then we recommend moving up a helmet size.
