The Nike ISPA OverReact Flyknit 'Shadowberry' features a unique design that eliminates the need for traditional laces. Instead, it utilizes a hook and loop closure on the Flyknit upper, which is constructed using excess yarns that determine the final color pattern. As a result, each pair becomes truly one-of-a-kind. The shoe boasts a lightweight build, complemented by a carefully engineered Nike React midsole that strategically adds extra foam in areas that require it the most. Additionally, the durable rubber outsole ensures optimal grip and traction under both the toe and heel.
