STEPN, a Web3 application, sells NFTs. What may not sound new at first is something special. The digital sneakers can indeed only be worn digitally. In this way, digital money can be collected. An app on the smartphone monitors the kilometres by GPS, which are then credited in the form of GMT, a cryptocurrency based on Solana. This is how money is supposed to be made through running. The only sticking point: a pair of sneakers costs just under 500 euros, and there are hardly any upper limits here either. Some users also complain about bugs that prevent the kilometres from being counted. So the project does not appear to be the revolution of NFT-based fitness. But perhaps it is a signpost to the future of Web3.
