Nike has patented shoes that are tokenized as a non-fungible token (NFT) on the Ethereum blockchain, dubbed CryptoKicks. The technology in the document describes an Ethereum ERC721 or ERC1155 token used to authenticate and transact a physical shoe. The token would then be unlocked with the purchase of the shoe by linking a 10-digit shoe identification code with the owner identification code. When the footwear is sold, ownership of the digital token can be passed on alongside the physical product.
Nike borrowed the idea for this project from the blockchain collectible cats game CryptoKitties, and Nike further suggests that the shoes, like CryptoKitties, can be 'bred' with each other to create a 'shoe offspring' and have that made as a new pair of custom shoes.
