Wherever you run, whenever you run, however you run — run free. Flyknit upper provides zoned stretch, support, and breathability where you need them most. Flywire cables holds the foot in place with adjustable lockdown through the laces. Low-profile injected unit sole foam is durable enough to double as midsole and outsole, drastically cutting down on weight for a featherlight, barely there feel. Anatomical rounded heel rolls at heelstrike, promoting a more natural running gait. Auxetic outsole pattern expands on impact and contracts at toe-off, following the natural movement of your foot throughout the running stride.
