The Nike ISPA Universal Grey features a futuristic shoe designed with waste reduction, longevity, and comfort in mind. This purpose-driven Grey Nike ISPA Universal boasts a zero-glue design, which means all the removable parts can be replaced. For example, the shoe comes with two 40 percent cork insoles that can be cleaned or replaced when they wear out. This means you don’t have to throw out the entire shoe. Another sustainable feature is the Bio-EVA foam. This durable, lightweight foam is made from nature-derived sources, such as sugarcane, instead of petroleum or other non-renewables. The sneaker features a chunky, molded silhouette and comes in grey. Crevices, bumps, and indentations in the Bio-EVA foam create dimension and give the shoe a rock-like appearance. Our experts like that this shoe’s purpose extends beyond performance in sports or style. Instead, it’s designed to make our world a better place. The Nike ISPA Universal Grey was released on June 15, 2023, and sold for $80.
