The Air Sock Racer, launched back in 1986, proved to be a pioneering creation, far ahead of its time. Even to this day, its distinctive design continues to influence numerous modern shoe designs. Originally destined for marathon runners, this shoe boasted a unique four-way stretch elastic mesh upper that resembled a cozy sock, supplemented with two supportive straps. Today's updated version, the Air Sock Racer Ultra Flyknit, elevates the experience with the incorporation of a Flyknit upper, a lighter Ultra outsole for enhanced comfort, and thicker straps that provide increased stability for the wearer.
