The Nike React City 'Black Sail' is a shoe specifically designed for urban runners, released in the summer of 2019. With a weather-resistant design and reinforced support, it is built to withstand the challenges of running on concrete surfaces. The shoe features a convenient slip-on fit, thanks to its knit collar and mesh bootie. Additionally, it incorporates a diagonal sealed zipper that envelops the foot, providing a laceless layer to keep out water and debris. To ensure visibility in low light conditions, the shoe includes 3M reflective taping. Furthermore, the React outsole, which incorporates data-informed technology, has extra rubber for enhanced durability during city runs.
