From the manufacturer:
"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 delivers the top-of-the-line performance of the best running shoe we make to every kind of runner. Whether you’re training for world-class competition, or catching a rush hour train, the versatile application of the 1080’s technological features allow you to do something more: more miles, more often, more comfortably. The 1080v12 fine tunes the cushioning, weight, and flexibility ratio that makes the 1080 so adaptable to the stresses that occur during the course of every run. Signature Fresh Foam X cushioning technology is paired with a lightweight, engineered knit upper, focused on breathability and stretch, and strategic supporting elements."
