On one side, the refined proportions of '70s running shoes: petite, unfussy, built for movement rather than spectacle. On the other, the technical DNA of 2000s running design, filtered through New Balance's own archive. The result is a low-pro shoe that reads sleeker and more compact than its Y2K-leaning siblings, the 740 and 530 models, without losing any of the character that makes retro tech style so wearable right now.
