I was wondering if anyone could help me here.

Im trying to find out what material is used in the out soles of badminton shoes.

I know(as far as i can tell.) that it is rubber but im trying to find out which specific rubber(elastomer) it is.

Is it natural rubber, synthetic rubber, a mixture of both or a completely different material

and if a synthetic rubber which kind.

Any help would be great or if someone could point me to a resource i could look at.

Thank You
