Using  pair of Head RD 130 Raptor ski boots and have question about them.

On the inside of right boot is a sticker that reads "Tech Chart"

Below heading are 5 lines that read

--Last  -- -RD

--Material ---HS1--HS2--HS3--HS4  (HS2 is check marked)

--Flex Index-- 130/140/150

--Sole Thickness---FIS Approved

--Canting---1,2 degrees

My question is what does the "Material HS2  mean"?

Are there various materials used in the same model boot?

My boots are marked with a check mark on HS2

Just curious what I have.

Thanks
