Unisex Sigma Aria (Sprint Track Spike)

The Sigma Aria strikes a unique balance of speed and endurance, perfect for seeking a smooth but aggressive transition from 200 to 400m. The plate shares a design with the more aggressive Sigma Harmony, but utilizes a less rigid material for a more forgiving ride over longer distances. A new engineered knit upper features external film for a secure and durable fit.

Suitable for 60-400m races.
