Satan Shoes were a series of custom Nike Air Max 97 shoes, created in 2021 as a collaboration between American musician Lil Nas X and MSCHF, a Brooklyn, New York art collective. Their design and marketing gained controversy through prominent satanic imagery. Nike, Inc. sued MSCHF for trademark infringement, false designation of origin, trademark dilution, and unfair competition. A settlement was reached in July 2021 which required MSCHF to offer refunds to any buyer who wished to return their shoes.
