Nike ISPA Universal Natural

Natural/Natural/Natural

Inside and out of the Nike ISPA, every detail has a purpose. The absence of glue means less waste. Bio-EVA foam, used throughout the design, is made with bio-based feedstocks derived from sugarcane. And each pair comes with two sets of moisture-absorbing, 40% cork insoles—once the first set breaks down, you can replace the insole instead of replacing the whole shoe.
