Nike's Waffle Racer is an icon. It’s been around since the brand’s earliest days and it doesn’t seem to be disappearing any time soon — especially now it’s being reworked. This women’s version, the Waffle Racer 2X, is just that. Lightweight ripstop forms the uppers and an embroidered Swoosh graces the sidewall, but the famous waffle outsole remains untouched and gives a nod to the brand’s innovative roots.
