Exotek Nitro is an architectural solution to tooling construction, it protects and stabilizes a soft EVA foam infused with NITRO. The structural ‘cage’ allows for a super soft, squishy inner midsole material. As the foam compresses, the cage provides the outer structure and stability needed whilst giving the wearer all the benefits of enhanced comfort. This silhouette draws parallels from both architecture and nature. The exposed structures of brutalist architecture, the rib cage of a human body protecting vital organs. This version is decked out in the insignia of SF for a unique and flashy motorsport look. SF Exotek Nitro Lace Up Sneakers
