Nike Have Released A Tribute To The Iconic Mercurials Wore By Ronaldo In 1998 - SPORTbible
Nike Mercurial Vapor IX SE FG MVXV (Ronaldo R9 1998) - Unboxing + On Feet - YouTube
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.
