Nike ACG Ultrafly 2 Sail

Built in the dirt and made for the wild, the Nike ACG Ultrafly 2 “Sail” is the supercharged sequel that trail runners have been waiting for. Forged through more than 30,000 miles of global testing, this next-gen model blends the bold DNA of Nike ACG with the propulsive tech of ZoomX racing foam. It’s not just built to survive your next adventure — it’s designed to help you fly through it.

At the core is a full-length ZoomX midsole sitting above a split carbon FlyPlate for next level energy return and torsional flex over gnarly ground. A rugged Vibram Litebase MegaGrip outsole with 3mm lugs chews through slick rocks and loose soil, while a redesigned fast draining upper and wider last deliver improved comfort and fit. Subtle tweaks like a slightly roomier toe box and extra heel space make this one feel more accommodating without losing that performance edge. Even the Swoosh and ACG branding go big for this round.

Whether you’re logging verticals in the Alps or eating miles through forest singletrack, the Ultrafly 2 “Sail” brings you lightweight cushioning, technical grip, and enough durability to outlast the terrain.
