Description
Fifth-generation super trainer blending speed and versatility. Retains signature snappy ride with incremental refinements. Highly regarded for its balance of performance and daily usability.
Delivers a firm, energetic ride with excellent turnover and control. Upper is notably breathable and secure, while the platform feels stable and responsive. Slightly increased rigidity and weight enhance support but reduce flexibility compared to earlier versions.
Ideal for runners seeking a single shoe for tempo runs, intervals, and race day. Performs well for daily training and moderate long runs, especially for those preferring a firmer, more structured feel. Less suited for recovery days or those prioritizing plush cushioning, but remains a top choice for versatile speed-focused training.
