SSR - Knight by Gaslight (Batman: Gotham by Gaslight) - 1/6th Scale Figure

[AlanJG1]

What material are the boots made of?

According to the SSR solicitation below, the boots, belt and wrist armor are all made of leather:
A tactical belt with leather
A pair of boots with leather
A pair of wrist armour with leather

On a side note, My AliExpress tracking finally showed that it shipped today.

Could be a language barrier, but "with leather" doesn't instill confidence that it's made of leather. Just that it has leather.
