The Nike ISPA Universal ‘Smoke Grey’ showcases a cutting-edge slip-on shoe that prioritizes sustainability and comfort. Constructed using bio-EVA foam sourced from sugarcane, this futuristic footwear offers a lightweight feel without compromising on durability. Its medium grey hue gives it a stylish and versatile appeal. The seamless design not only exudes a modern aesthetic but also includes a pockmarked texture, sculpted lines, and irregular vents on the vamp, ensuring enhanced breathability. For added convenience, each pair of these sneakers is accompanied by two sets of moisture-absorbing insoles. These insoles, composed of 40% cork, not only contribute to a more comfortable experience but also bear the signature Nike ISPA branding, adding a touch of sophistication to the overall design.
