Thinking of signing up for a 5K or 10K this year? You might want to improve your kicks: the new Nike ZoomX Streakfly is designed for exactly these kinds of events. Utilizing proven Nike innovations such as ZoomX foam, the new shoe is optimized for short-distance running on pavement.
“We learned that there was a small gap in our running line between what we offered for full marathon and half marathon and what we offered for track competition,” said Elliott Heath, Product Manager shoes at Nike Running, in a press release. . “To better serve athletes running and training on the roads for 10K and 5K, we set out to develop a shoe that would still give them a comfortable, lightweight and propulsive ride with more connection to the ground.”
Compared to racing models like the Alphafly, with its chunky sole and Zoom Air unit, the ZoomX Streakfly has a decidedly streamlined silhouette. It features a ZoomX midsole (Nike’s lightest, most responsive foam) that runs the full length of the shoe. While other Nike running shoes use a carbon fiber plate in the midsole for a snappy underfoot feel, the Streakfly has a Pebax plate built into the midsole in the midfoot. This provides additional stiffness and response, but the shorter plate helps reduce stack height, giving the shoe a low-to-the-ground feel. Translation: This shoe is designed to be springy and fast on the pavement.
The upper is made from a technical mesh adapted to the different areas of the foot. Towards the front of the shoe, the mesh is designed for more structure and support around your foot, but features a more open pattern at the rear for improved breathability and reduced weight. Nike also added a contoured heel counter to the upper for a more comfortable fit. Overall, the upper provides support where you need it without weighing your feet down.
Nike also paid attention to grip. The ZoomX Streakfly features a unique ridged pattern on the outsole, the product of extensive data collection of runners’ stride patterns. Based on this data, Nike has refined the outsole design for optimal traction on the road.
The final result ? A fast and versatile shoe for shorter distances.
“In addition to being an approved road running shoe, we expect athletes to use it as part of their training on both the road and the track,” says Heath. “For runners who may not want to jump in spikes, or those who run on a surface that doesn’t allow them to be in spikes during their training, the Streakfly is a perfect solution.”
Initially, the shoe will be offered in “Prototype” white, but Nike promises that more colors are on the way. It’s not super splashy, but it does have some cool details, including a “5K/10K” tag – a nod to the shoe’s intended use – and a wear test number on the side medial of the outsole, a reference to the wear testing process that Nike uses to develop its models.
The shoe will retail for $160 and go on sale next month.
