If we only made one running shoe, that shoe would be the 1080. What makes the 1080 unique isn't just that it's the best running shoe we make, it's also the most versatile. The 1080 delivers top-of-the-line performance to every kind of runner, whether you're training for world-class competition, or catching a rush hour train. The Fresh Foam X 1080v12 represents a consistent progression of the model's signature qualities. The smooth transitions of the pinnacle underfoot cushioning experience are fine-tuned with updated midsole mapping, which applies more foam to wider areas of the midsole and increases flexibility at the narrower points. The ultra-modern outlook is also reflected in the 1080's upper construction. The v12 offers a supportive, second-skin style fit with an engineered Hypoknit upper, for a more streamlined overall design.
