The React Element 55 is the opaque version of the highly popular React Element 87, which became one of the most talked about sneakers of 2018 thanks to its cutting-edge design that features a transparent upper. The React Element 55 delivers the same comfort thanks to the full-length React foam cushioning, but the upper has a more traditional solid textile construction. The Nike React Element 55 “Black/White” features a strong two-tone look in black across the upper with a white midsole and accents.
