1998 OG Nike Mercurial Vapor R9 SG sz. 8.5 Made In ITALY | eBay
Nike Mercurial Vapor R9 Limited Edition | Nike air max mens, Nike shox turbo, Nike air huarache
I believe these are the mercurial r9 from 1998. I remember having a pair with the same colorway but without cleats. For indoor soccer I believe but can't find any info online.
