The road running shoe for city streets gets a performance upgrade with soft Helion superfoam and breathable fabrics. The shoe's snug bootie construction is updated with a single-piece knitted upper for maximum airflow. The perforated toe box further boosts breathability. For a cushioned yet energetic ride, the midsole's top layer is made with soft Helion superfoam, while denser foam on the bottom provides a more propulsive push-off. Plus, it's now finished with a new knit material for a more modern look.
