The Sidi Dust Gravel Cycling Shoe features a lightweight yet extremely durable construction, allowing for an efficient transfer of power from our foot through the pedal. Lining the top of the foot is the Techo-3 system, using a buckle and Sidi's reliable Wire to provide an equally distributed tension with a quick adjustment. The polyurethane inserts add extra traction on hike-a-bike sections, while a reinforced heel cup provides the extra comfort we need for long rides.
