Nike ACG Ultrafly Trail Men'S Running Shoes - Racer Blue

The Nike ACG Ultrafly Trail is a men's trail running shoe built on a ZoomX midsole, a dual-plate carbon setup, a Vibram Megagrip Litebase outsole and an Engineered Mesh upper. It takes you through long efforts on trail, with neutral support. **Product Highlights** * Heel drop: A 9mm heel-to-toe drop. A higher drop eases load on your calves and Achilles tendon. * Midsole foam: ZoomX foam gives high cushioning and propulsive energy return. * Plate: The dual-plate carbon setup stiffens the forefoot while keeping torsional flexibility. A firmer toe-off helps you hold pace as fatigue builds. * Outsole: Vibram Megagrip Litebase rubber. It grips gravel, loose dirt and wet granite. * Upper: Engineered Mesh with a mesh lining for a roomy fit. * Reflective details: Reflective elements aid visibility in low light. * Fit and sizing: Fits true to size, standard width only. Expert reviews flag inconsistent heel lockdown for narrow heels. **Best For** * Ultra-distance races on gravel and fire roads * Road-to-trail runs across tarmac and dirt * Cold-weather trail training
