Some shoes have multiple versions of what is essentially the same shoe, with variations in style or materials. We try to group these together. Retailers sometimes list a version number wrong, and our system can treat those mislabeled names as variants.
How it ranks
The Nike ACG Ultrafly Trail’s rating is an early estimate. We’ve collected 1 runner review so far, with brand history and external ratings also informing the score.

Confidence
