Nike All Conditions Gear is back, this time with a full trail running lineup

Nike is relaunching All Conditions Gear as a dedicated outdoor brand, and the first products are built for trail runners. It’s a real reset. ACG has existed since 1989, but spent the last decade drifting toward streetwear instead of trail performance. This time, Nike Trail is being folded into ACG completely, and every product in the new lineup is built for people actually logging miles on dirt.

What’s in the lineup

ACG Ultrafly is the flagship trail shoe, built with a carbon plate, ZoomX foam, and a Vibram outsole. The plate is split down the center so it flexes over uneven terrain, and the upper drains water quickly for wet courses.

The Zegama is built for longer efforts, with max cushion, a wider toe box, and a rock plate for technical terrain

On the apparel side, the Lava Loft Down Jacket weighs 10 ounces and packs into its own pocket. It uses 700-fill down with ventilation perforations placed where trail runners tend to overheat.

Radical AirFlow racing top is designed around maximum breathability during high-output efforts in heat.

All four products were developed with ACG’s All Conditions Racing Department—28 elite trail runners across eight countries who test prototypes and give feedback.

Trail running reaches a new scale

Trail running participation in the U.S. has grown more than 25% in a few years, but the category has mostly belonged to outdoor-first brands like Salomon and Hoka. ACG is Nike’s first serious attempt to compete here with purpose-built gear rather than adapted road shoes.

Where to shop

The Ultrafly and Lava Loft are available now at AllConditionsGear.com. The Zegama and Radical AirFlow top arrive in summer 2026.
