Nike ISPA Universal (Natural)

A futuristic, eco-conscious slip-on that prioritizes modularity and circular design. The ISPA Universal is injection-molded using a single-piece Bio-EVA foam, featuring an organic, bone-like rippled texture and strategic perforations for breathability. This "Natural" colorway offers a clean, neutral look, while the replaceable moisture-absorbing cork insoles ensure the shoe remains functional and sustainable for long-term wear.
