Sportswear brand Nike is suing Brooklyn art collective MSCHF over a controversial pair of "Satan Shoes" that reportedly contains a drop of real human blood in the soles.
The US$1000 sneakers, which feature an inverted cross, a pentagram and the words "Luke 10:18", were made using modified Nike Air Max 97s.
The company released 666 pairs of the shoes on Monday in collaboration with rapper Lil Nas X and says they sold out in less than a minute.
Nike is claiming trademark infringement.
In a lawsuit filed in the US District Court for the Eastern District of New York, the sports shoe company said it did not approve or authorise the customised "Satan Shoes".
Nike is asking the court to stop sales of the shoes and prevent the use of its famous Swoosh design mark.
