AN ELEMENT OF SURPRISE. The Nike React Element 55 borrows lines from OG Nike running shoes like the Internationalist, adds reflective graphics, and then places it all on the unbelievably soft and supportive Nike React cushioning. Splashes of bright, contrasting colors throughout add the perfect amount of edginess. Nike React technology delivers an extremely smooth ride. Bright, contrasting colors add heart to the winter. The lightweight upper has a high sheen for an elevated look and features lightweight, no-sew skins. The eyestay foxing follows the wavy design lines of the Internationalist for added Nike heritage. TPU heel clip provides a stable feel while adding OG running heritage.
