Nike ACG Ultrafly: The Ultimate Trail Running Shoe is Coming in Spring 2026

For those familiar with running shoes, the mere mention of 'Zoom X' is enough to understand the extent of Nike's performance technology. Now, a truly exceptional 'trail running shoe' is on its way.
And it's a collaboration with the ACG brand.
Coming in Spring 2026, Nike will release a new trail running shoe called the ACG Ultrafly.
This model isn't just for casual walks.
It's a high-performance shoe for serious trail running, touted as the most powerful trail-specific model in Nike's history.
