The rapper/pop star is putting out a limited release of Nike sneakers that are all about the Prince of Darkness and his kingdom ... right down to the box artwork and even the shoe design itself, which features a pentagram emblem sitting on the laces.

Check out the photos ... they're not leaving much to the imagination here.

The shoe body is a Nike Air Max '97, which MSCHF -- the company behind this campaign -- has reinvented with Nas X's new 'Montero' song and video in mind. It's got a bible scripture emblazoned on the side, Luke 10:18, which references Satan's banishment from heaven.

There's also a 666 reference toward the back of the shoe ... with another number in front of it, alluding to which limited unit it is. Word is, MSCHF/Nike are only dishing out 666 of these puppies to the public ... so if you have 6/666, that seems to mean you got the 6th model.

Here's the kicker ... apparently, these shoes will contain one drop of human blood somewhere along the soles. And no, not the metaphorical blood, sweat and tears of the factory workers who will presumably put these together ... like, actual plasma-filled red stuff.

Unclear whose blood exactly is being used for this ... but it's provocative, without a doubt.

Of course, the collab follows Nas X dropping a visual project for his track 'Montero (Call Me By Your Name)' ... which got a lot of mixed reactions this past week.

It depicts him descending into hell and cozying up to Lucifer himself ... and giving him an erotic lap dance, no less. Some loved it, saying it's a celebration of Nas X's sexuality. Others, including some parents, felt it was over the top and NSFW ... especially considering Nas X's younger audience, aka children, who came to know/love him through 'Old Town Road.'
