Men's Nike ZoomX Ultrafly Trail (D-Width)

Nike Ultrafly Men’s Trail Racing Shoe Engineered Speed for the Unpredictable Trail

The Nike Ultrafly is not just a shoe—it’s a precision tool built for athletes who race mountains, crush climbs, and descend like gravity doesn’t apply. Designed for serious trail runners and ultra-distance racers, the Ultrafly marks Nike’s boldest leap yet into competitive trail footwear, bringing cutting-edge road racing technology into the unpredictable wilds of nature.

At the heart of this innovation is the carbon Flyplate, a first for Nike Trail. Sandwiched between the brand’s ultra-responsive ZoomX foam and a durable knit fabric-wrapped midsole, the plate delivers explosive propulsion with every step. Whether you're powering up alpine switchbacks or finding your rhythm deep into mile 50, the Flyplate adds a snappy, forward-driving feel that helps maintain momentum when fatigue sets in. It’s the kind of technology that turns effort into velocity—essential when seconds count and the terrain pushes back.

But speed without traction is wasted. That’s why Nike collaborated with Vibram, the leader in high-performance outsoles, to develop an exclusive Ultrafly outsole that fuses Vibram Megagrip, Litebase, and Traction Lug technologies. The result? A sticky, lightweight grip system that grabs onto everything from wet roots to dusty ridgelines. The chevron-patterned lugs bite into loose ground going uphill and offer control and braking confidence on steep descents. Whether it’s raining, dry, or a mix of both, the Ultrafly’s grip adapts and performs.

• Stability is another cornerstone of the Ultrafly’s design. A flat-bottom platform reduces the instability often associated with carbon-plated shoes, while the minimized cross rocker enhances balance on uneven surfaces. Combined with the engineered midfoot support zones, the shoe wraps your foot securely without bulk, letting you pick lines through technical terrain with precision and speed.
• Durability hasn’t been sacrificed in the name of speed either. The midsole is encased in a protective fabric wrap, shielding the ZoomX foam from trail abrasion while maintaining flexibility and cushioning. The upper, made from Nike’s lightweight Vaporweave mesh, provides high breathability and resists water absorption—ideal for creek crossings, misty ridgelines, or hot, dry races.

With a heel-to-toe drop of 8.5 mm and a weight of approximately 300g (Men’s size 10), the Ultrafly strikes a sweet balance between race-day lightness and trail-ready toughness. It’s built for endurance without compromise—ideal for 50Ks, 100Ks, and mountainous ultras where the terrain changes but your ambition doesn’t.

Ideal Use Case:

The Nike Ultrafly is built for competitive trail racing and high-performance training on mountainous, mixed-condition trails. It’s perfect for runners tackling long distances at speed—especially in events where terrain ranges from technical and muddy to fast and flowy. This shoe shines on races like UTMB, Western States, or local mountain ultras, where lightweight propulsion, grippy versatility, and long-haul comfort are non-negotiable.

Whether you’re chasing podiums, personal bests, or the thrill of pushing your limits in nature’s wild playground, the Nike Ultrafly delivers. It’s the culmination of Nike’s best road racing tech, tuned precisely for the trail—because the finish line isn’t always paved.
