Olympic athlete Allyson Felix posted a black-and-white advertisement on her Instagram account for her Saysh shoe brand, which shows her adorned with medals as she says, “Like so many of us, I was told to know my place. But here I am, ready to run for a brand that I founded, designed for and designed by women.” The brand is auctioning a bespoke pair of Saysh 0.07 Spikes that Felix wore during the Games, as well as a nonfungible token, to raise money for The Power of She Fund: Child Care Grant.
