Fine-tuned for CrossFit, Reebok's Nano 9 is a neutral sneaker designed to adapt to the demands of rigorous training sessions. This 'White Primal Red' update—debuted in June 2019—has a Flexweave upper re-engineered for advanced flexibility and a contrast logo overlay. The rubber protection wrap is captured in a striking hue. Underfoot, full-length midsole cushioning and a decoupled outsole with a Metasplit groove pattern combine to promote a stable feel.
