The Nike ISPA Universal 'Natural' is a casual slip-on shoe that perfectly embodies Nike's commitment to sustainability through its 'Move to Zero' initiative. Drawing inspiration from three iconic models - the Air Max 270, the Zoom Type, and the Solarsoft HTM - this sneaker is constructed using hand-buffed EVA foam, which is made from bio-based feedstocks sourced from sugarcane. Enhanced breathability is achieved through perforated detailing throughout the upper, while the inclusion of a 40% cork insole ensures moisture absorption and a personalized fit that conforms to the foot's shape over time. Furthermore, the shoe's lightweight cushioning is provided by the encapsulated foam midsole, delivering exceptional comfort with every stride.
