Nike put out the original Nike React Infinity in 2019 as a running sneaker that was specifically designed to help runners avoid injuries. The company tinkered with the initial design and released the Nike React Infinity Run Flyknit 2 White just two years later. This Nike React Infinity sneaker included an almost all-white Flyknit upper that was designed to make it breathable. It also had Flywire technology worked into the mix to make the sneaker supportive. Nike incorporated high foam heights into the second Nike React Infinity sneaker as well to provide added comfort and cushioning. The best aspect of this sneaker in our expert opinion, though, is the subtle hint of pure platinum that offsets the white used elsewhere. It makes these running sneakers shine even more than they would otherwise. The Nike React Infinity Run Flyknit 2 White was released on April 19, 2021, and it originally retailed for $160.
