Nike Air Zoom Alphafly NEXT% Running Shoes

Gear up for your next personal best with the Nike Air Zoom Alphafly NEXT% Flyknit Ekiden. It gives you the greatest energy return of all Nike's racing shoes with a propulsive feel through the finish line. The design is light, breathable and backed by data to help keep you comfortable.

FlyKnit-AtomKnit Upper

Atomknit uppers encase the foot in lightweight comfort. The comfortable updated version of Flyknit is steamed and stretched to deliver a lightweight and contoured fit. The fabrication wraps the foot in lightweight support to ensure a comfortable and secure fit from the moment you put them on till the moment you take them off. The minimalist fabric sits close to the foot to ensure a dynamic, lightweight fit that's ideal for racing whilst perforations within the fabric increase airflow, creating a better, healthier environment for your feet to thrive in. The breathable upper allows cool air to flow into the construction whilst, at the same time allowing hot, humid air to escape so you can remain cool, dry and comfortable at all times. With added water reduction the Alphaweave upper keeps your feet protected during light rain. A one-piece construction seamlessly integrates these areas of high breathability with stretch and support where you need it the most, adapting to the changing shape of your foot as it moves through the gait cycle and reducing slippage so that you can enjoy smooth, distraction-free speed. It swathes your foot in lightweight support and a seamless, sock-like fit - shrinking the risk of rubbing and blisters. Completing the upper is a lacing system that locks down the midfoot so you can enjoy distraction-free strides.

ZoomX Midsole

Nike's ZoomX is lighter, softer and more responsive than any Nike foam, designed to maximize speed by delivering greater energy return. ZoomX was derived from a foam traditionally used in aerospace innovation, applied for the first time in performance footwear. The ZoomX midsole in this shoe is a lightweight cushioning providing you exceptional comfort and protection for your feet. The foam construction also delivers an impressive 85% energy return, giving you the propulsion that you need from a racing shoe. Combined with this is 2 slim visible Zoom Air units, which assists you with more energy return. A full-length Carbon-Plate is also integrated into the shoe and delivers a snappy sensation with each stride. Nike has scaled the thickness of the plate for the size of each shoe-it is more flexible in smaller sizes and gets stiffer as the size of the shoe increases, which means that every runner has the same propulsive sensation no matter their size.

Durable Rubber Outsole

Using data from hundreds of different runners, Nike has created the perfect gripping outsole. The design places optimal rubber on the road for efficiency and traction; high-abrasion rubber adorns the rearfoot to increase durability, resisting the traumas of heel-strike to supply you with a reliable and long-lasting running buddy. Lightweight foam rubber covers the forefoot to provide grip and durability whilst enhancing energy return. Lengthwise flex grooves have been used on the rubber outsole to enhance multi-surface traction ensuring confident footing wherever your next race takes you. The durable rubber provides a strong grip and works to protect itself from damage, and protect users from losing control and slipping. It's all for the athletes who crave a shoe that's hard to run slow in, a shoe that allows you to maintain any given pace.
