The Nike ISPA Universal ‘Natural’ presents a casual silhouette that aligns with Nike’s ‘Move to Zero’ sustainability initiative. Inspired by three classic models (the Air Max 270, the Zoom Type and the Solarsoft HTM), the slip-on is crafted from hand-buffed EVA foam, featuring bio-based feedstocks derived from sugarcane. Perforated detailing throughout the upper provides improved airflow, while a 40% cork insole absorbs moisture and eventually molds to the shape of the foot. An encapsulated foam midsole yields lightweight cushioning with each step.
