Nike Mercurial Vapor IX 1998 R9 15th Anniversary Limited Edition - SIZE US 11 | eBay
Nike Mercurial R9 Ronaldo Soccer Cleats Shoes Size 2 Y Vintage Retro 1998 style | eBay
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.
