The Nike ISPA OverReact Sandal “Thunder Grey” consists as one of the silhouette’s inaugural colorways. Flaunting a blend of utilitarian and deconstructed sensibilities, the model’s eye-catching profile is notably directed at the tooling which carry a disproportionate tread pattern as an ode to improvised traction systems and adapting the OverReact pattern. The upper is composed of textile, leather, and nubuck overlays that provide structure and allow free airflow.
