Boom grip is not EVA as most people think EVA is softer, it's PU.
PU and EVA come in varying densities. Either can be hard to spongy . EVA is stronger and doesn't rip as easily , PU is more slippery and cheaper . I use a medium density EVA for re gripping booms. ( I can let you know the exact density). I believe most boom grips to be EVA. The ones that fall apart earlier , North , for example are just a softer grade .
