The Nike ISPA Universal ‘Smoke Grey’ delivers a futuristic slip-on built with lightweight bio-EVA foam derived from sugarcane. Crafted with a sustainable zero-glue design and finished in a medium shade of grey, the seamless build features a pockmarked texture, sculpted lines and irregular vents throughout the vamp for improved breathability. Each pair comes with two sets of moisture-absorbing insoles, made with 40% cork and accented with Nike ISPA branding.
