Meet our lightest racing shoe. The Streakfly is all about the speed you need to take on the competition in a mile, 5k or 10k race. With a low-profile design and sleek details, it feels like it disappears on your foot to help you better connect with the road on the way to your personal best. Low and Nimble Full-length ZoomX midsole provides the ultimate lightweight responsiveness. The foam stack heights are lower than the Vaporfly, saving weight and giving you a more aggressive feel. The result is a shoe so light, it disappears on your foot while still giving you the responsive cushioning of ZoomX foam, helping you reach your fastest pace throughout the turns and accelerations of any race. Supportive and Sleek Ultra-thin knit upper is light in weight while still providing the support you need for racing. Extra reinforcement in the forefoot keeps you secure. An updated, sleek lacing system is laterally offset with a notched tongue to help relieve pressure on the top of the foot. Grip for Days Runner-informed data was used to create the outsole and place traction where you need it most with a pattern that connects to the pavement based on how your foot hits the ground. The result is solid grip from foot contact to toe-off, helping you stay ahead of the competition.
