This model runs large, compared to previous versions. You may consider ordering down from your normal size. 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.
