Six-time Olympic champion Allyson Felix has launched her own shoe brand in the build-up to this summer’s Tokyo Games.
Felix said in 2019 that Nike wanted to pay her 70% less after she became a mother, before the company changed its contracts for pregnant athletes.
She later decided not to renew her contact and instead joined a women’s athletic wear company.
Felix, 35, returned to the track two years ago after life-threatening complications arising from the birth of her daughter Camryn, who spent her first month in intensive care.
She took part in the United States trials for Tokyo 2020 and qualified for her fifth Games with a second-place finish in the 400m.
