The Specialized S-Works SUB6 Road Shoe is the most aerodynamically advanced, lightest shoe Specialized have ever produced. The traditional lacing system cuts down weight, while the Warp Sleeve lace cover - a sleeve worn directly over the laces - is Wind Tunnel Engineered to reduce drag and clean airflow over the shoe. When combined with the narrower heel cup, you can save up to 35 seconds over 40 kilometres when compared to the previous S-Works Road Shoe. With the PadLock heel, it maintains the same secure and snug heel fit as the all-new S-Works 6 shoe for superb connection and efficient power transfer, but in a bold yet minimal package. Less is more.
