Built for achieving your personal best, the Rocket X 3 delivers a carbon-fiber super shoe that doesnt skimp on support. Maintaining the same responsive, high-performance foam as its predecessor, weve updated our pace-pushing carbon fiber plate with new winglets and employed a sticky rubber outsole to inspire confidence in variable conditions. Enlisting a single-layer engineered mesh upper for enhanced breathability and stitch-and-turn collar to help mitigate blisters, weve removed the gusset for easier entry.
