Things could get nasty for rapper Lil Nas X.
The Holiday hitmaker collabed with New York firm MSCHF to produce so-called Satan shoes, which reportedly contain a drop of human blood in the soles.
The black and red, devil-themed shoes are customized Nike Air Max 97, writes Reuters, and feature the distinctive Nike tick.
Now Nike is suing MSCHF for infringing and diluting its trademark.
Lil Nas X, real name Montero Lamar Hill, was not named as a defendant.
The words "MSCHF" and"Lil Nas X" are written on the back of each shoe.
Only 666 pairs of the limited edition skoene went on sale online on Monday. They were said to be sold out in under a minute, costing $1018 (R15 200).
undefinedThe takkies seem to complement the release of the Grammy-winner's video for his new song, titled Montero (Call Me By Your Name), in which he dances with a character wearing devil horns.
Nike has distanced themselves from the shoes, saying it did "not approve or authorise" production of the shoes, and wants the court to halt further sales.
