The S-Works Sub6 is the most aerodynamically advanced, lightest shoe we’ve ever produced. The traditional lacing system cuts down weight, while the Warp Sleeve™ lace cover—a sleeve worn directly over the laces—is Win 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 theall-new S-Works 6 shoe for superb connection and efficient power transfer, but in a bold yet minimalist package. Less is more.
