Launching as part of the brand’s innovative and experimental line, the Nike ISPA OverReact Sandal ‘Thunder Grey’ delivers an ultra-responsive ride, highlighted by a stacked Nike React midsole that adds foam cushioning where it’s needed most. A rugged tread pattern is utilized on the sidewalls and outsole, the latter featuring durable rubber at the toe and heel for off-road traction. The airy deconstructed upper combines webbing straps and a drawcord lacing system for a secure fit.
