The Zoom Fly 6 sits in Nike's training range rather than its racing one, built around a full-length carbon FlyPlate and a ZoomX-over-SR-02 foam stack that holds up to repeated mileage. 'Dark Obsidian Racer Blue' runs a deep navy across the engineered upper with a brighter blue on the Swoosh and midsole trim. Both tones sit in the same family, so the shoe reads tonal from a distance. The thin mesh upper adds little weight over the stack.
