- Nike Mercurial Superfly 6 Elite match issued to global footballing icon Cristiano Ronaldo during the latter stages of the 2017/18 season whilst playing for Real Madrid CF.
- This was the final Mercurial model Ronaldo ever wore as a Real Madrid player, marking the conclusion of his legendary nine-year spell at the club.
- Issued to Ronaldo directly from Nike’s Athlete Services facility in Montebelluna, Italy, where all of his bespoke Real Madrid match boots were hand-built.
- Each boot was originally personalised with the names of Ronaldo’s children — “EVA MARIA”, “ALANA MARTINA”, “CRIS JR.” & “MATEO” — which were later partially removed but remain faintly visible beneath the finish.
- Features ‘CR7’ branding on the front of the dynamic fit collar, exclusive to Ronaldo’s personal issue pairs.

- Internally, each boot displays Ronaldo’s handwritten custom foot last/mould ID number in place of any size label, confirming its bespoke Montebelluna origin.
- Custom insoles feature the CR7 logo, Nike Swoosh, and “Born Leader” crest — surrounded by inscriptions reading: “European Champion • All Time Top Scorer • Most Capped Player • Orgulho Nacional” (“National Pride”).
