Since jetting into Manchester, the Belgian striker has never had a solid boot supplier backing him. He's been spotted wearing Adidas, Nike and PUMA for the last year.
Lukaku made headlines during United's pre-season camp in Los Angeles at the start of his stint, when he was seen laced up in the Adidas NEMEZIZ, which he seemed set to stick with.
We all know this wasn't the case. Soon after his NEMEZIZ appearance, the big striker brought out Nike's Hypervenom. Since then, the only way to describe Lukaku's boot saga is to call it; a 'roller coaster'.
This Premier League season, we've seen him in Nike's Mercurial Vapor and the Hypervenom as well as Adidas' X 16.1 and X 17.1.
What's next for Belgium's number one striker? This year holds the World Cup and you would think that the big brands will be jumping at the chance to have Lukaku in their boots when it comes to Russia 2018.
