Nike ACG Ultrafly Trail

Ultralight foam and enhanced grip fuel your trail speed.

The Ultrafly 2 takes what you love about the original and refines it, so you can go the distance. The springy ZoomX foam is more responsive and the full-length carbon plate is softer for a smooth ride. The outsole helps reduce weight while maintaining enhanced grip as the miles pile up.

Product Highlights

• ZoomX Foam - Ultra-responsive ZoomX foam midsole delivers Nike's highest energy return with a stable feel for the trail. The foam is “unwrapped” in the heel for even better responsiveness.
  
• Breathable Mesh Upper - Don’t worry about puddles or streams—the upper is made for water drainage. It’s also lightweight, durable and breathable.
  
• More Flexibility - Tackle technical terrain with the full-length carbon fiber plate. We reduced the stiffness compared to the original Ultrafly for better control on the trails.
  
• Enhanced Grip - Go the distance with Vibram® Megagrip outsole. It’s designed to give you durability and enhanced grip on wet terrain.
