Fast. Aggressive. Sleek. Three descriptors lead to one goal with the new Sigma Aria from New Balance. It's built to give the experienced sprinter speed and endurance to crush goals from 200m to 400m. The plate shares a design with the more aggressive Sigma Harmony but uses a less rigid material for a more forgiving ride over longer distances. A new engineered knit upper has external film for secure support.
Unisex fit. Women should order 1.5 sizes smaller than usual.
