The England prop hopes his toe-jobbing will earn some Joe-mobbing – from foot fetishists lapping up his new sideline.
Marler is putting his heart and sole – or two – into the venture as he goes from Red Rose to pink toes.
The 88-cap star even released a teasing “erotic” video to promote the account on the X-rated website.
At 33, he might be close to hanging up his boots – in rugby.
But now he has found a reason for just taking them off – in jest.
Staring directly at the camera more like a veteran of adult entertainment, Marler tried to persuade 400,000 Instagram followers to come to heel.
He socked it to ’em with: “Hey you, yeah, you, I’ve seen the way you’re looking at my feet.
“9/10 certified by a foot health specialist. Want to get your hands on these trotters? Well now you can. Head on over to @JoseMalaTrotters on onlyfans.com.”
But warming to his theme, he added: “Be careful though, feel the heat in here? It’s from my feet.
“They’re clean as well, really clean. Unless of course you want them to be… dirty.”
That last line, however, was too much even for Marler himself.
His mask of deadpan delivery slipped right off as he burst out: “Urgh, I feel disgusting saying that sentence!”
And many of Marler’s fans also felt conflicted.
One found his his clip “disturbing yet strangely hot” and another joked: “Not sure if I am aroused or disgusted”.
A third claimed his kids were “scared and traumatised” by the corny video.
But a fourth reckons OnlyFans could provide Marler’s “retirement fund”.
And plenty of followers urged him not to change, saying “Love this guy” and “You crack me up”.
With responses like that, maybe he’s nailed it after all with his fun feet foray.
