Meet our lightest racing shoe. The Nike Streakfly is all about the speed you need to take on the competition in a mile, 5k or 10k race. A low-profile design with 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 ZoomX in the midsole provides lightweight responsiveness. The foam stack heights are lower than the Vaporfly, saving weight and giving you a more aggressive feel. It results in a shoe so light, that it disappears on your foot while still giving you the responsiveness of ZoomX foam—helping you reach your fastest pace throughout the twists and turns of a road race. Supportive and Sleek The ultra-thin knit upper is super light while still providing the support you need for racing. Extra reinforcement in the forefoot keeps you secure. And the updated, sleek lacing system is laterally offset with a notched tongue to help relieve pressure on the top of the foot. Grip Where It Counts Runner-informed data was used to create the outsole. It uses that information to place traction where you need it the 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.
