Engineered knit upper with synthetic textiles and cotton in a single knit design. Synthetic overlays. Rubber outsole. Magnetic closure speed lacing system. Full-length carbon fiber plate. FuelCell midsole cushioning. Molded Stone Island compass logo at the heel. Co-branded foxing, tongue label, and sockliner. For their latest collaboration, New Balance and Stone Island present the debut FuelCell C_1 colorway featuring a palette and camouflage pattern inspired by archival Stone Island garments. The shoe’s upper combines synthetic materials and cotton into a single knit, reflecting the Italian fashion brand’s legacy of textile innovations. A full-length FuelCell midsole and carbon fiber plate are incorporated to make this a performance-ready runner, while exaggerated design elements including the outsole that extends beyond the heel serve as more than mere aesthetic embellishments, with the added weight providing a counterbalance to the toe push-off, energy returning feeling of FuelCell.
