Nike ZoomX Ultrafly Men's Trail Running Shoes

Manifest your mountainous best when the trail ahead is skiddy and uncertain. This is Nike's all-new championship trail racing shoe, melding the brand's best speed components from the running world with what you need to plant your flag 1st at the finish line. It offers peak performance, sleek speed and endurance for those who want to summit nature's playground.

Vapor Weave Upper

A Vapor Weave upper encases each foot in streamlined comfort. Zones of ventilation and structure are engineered into the material; the Vapor Weave upper increases airflow to create a better, healthier environment for your feet to win in, and lightweight support wraps the foot in a firm fit, reducing in-shoe slippage so that you can enjoy smooth, distraction-free strides. Made from abrasion-resistant materials, the shoes are highly durable, providing excellent protection for your feet and shoes on the ever-changing trail. Known for its lightweight and low water retention, the Vapor Weave fabric keeps the shoe light even when wet. The anatomical toe design follows the foot's natural contours, enhancing propulsion by increasing space in the forefoot, allowing the toes to splay and push off the ground. Completing the upper is a traditional lacing system to help lock the midfoot down to prevent any excessive movement.

ZoomX Midsole

Nike ZoomX foam delivers Nike Running's greatest energy return yet, the Ultrafly adds more ZoomX for responsive comfort on race day. Ultra-light and super-responsive, the midsole material delivers Nike's greatest energy return yet; it absorbs impact and then expels it back out for a bounce-like effect. This energy-return technology reduces the use of superfluous muscle power, diminishing fatigue and enhancing performance, keeping you going for longer. The revolutionary ZoomX foam is manufactured from Pebax, a product conventionally used in plastic bridges and other moulded parts, and yields cushioning that is not only lightweight but soft and springy. Until now, these three characteristics (collectively) have proven nearly impossible to achieve. Pebax has a lower density than some thermoplastic alternatives, and this makes it lighter, flexible and more impact-resistant, whilst giving it a higher capacity for energy return. When blown into a foam, these properties remain, gifting you with a lively underfoot feeling that encourages you to run fast. Signalling the incredible resilience of ZoomX, the tiny creases that occur on every midsole do not have an impact on the foam's performance; these beauty marks are a result of the autoclave process, which places the foam under extreme heat and pressure. The ZoomX sheets are then compressed in a Phylon preform, which shapes the midsole parts. Because the special foam is so lightweight (one-third the weight of Cushlon), Nike is able to use more of it to separate your foot from the road; this means you get a thick and supportive midsole that will spare your joints as you strike down onto hard, unforgiving concrete. A newly redesigned, aerodynamic heel is designed to delay air separation and reduce drag, tapering to banish every barrier between you and your top speed. Embedded within the generous ZoomX platform, and complementing its responsive nature, is a full-length carbon Flyplate. Intended to minimise energy loss during toe bend without increasing demand on the calf, it springs up under your heel as you stride forward, yielding the snappy, propulsive sensation that converts into extra-energised strides. The plate is curved at the front, helping give the runner back some of the energy they put in at toe-off. The midsole is wrapped in fabric to cushion the foam from the elements and abrasion of being on the trails.

Vibram Exclusive Ultrafly Outsole

The Nike ZoomX Ultraflys feature a combination outsole. It is made in part with impressive Vibram Megagrip, which ensures traction and grip on varied terrain. This high-performance rubber compound gifts you with an unparalleled grip on wet and dry surfaces, rugged longevity and optimal ground adaptability. The rubber can form a solid bond with the ground beneath it to ensure traction and control as you explore the unbeaten path. This is combined with Vibram Litebase, which reduces 30% of the overall sole weight through a reduction of the sole thickness by 50%, while maintaining Vibram quality in grip, traction and durability. The shoes have a new Traction lug construction which supplies you with better traction on gravel and loose dirt, allowing you to tackle awkward ascents and difficult descents. A heel-to-toe rocker provides a smoother transition through your running gait while a flat bottom and minimised cross rocker give you optimal stability on the trails.
