Hyperlight-XC sole made from 100% unidirectional carbon with a stiffness index of 14.0 for maximum power transfer. The Michelin rubber inserts with dual-layer compound technology are 28% more abrasion-resistant than TPU and provide excellent grip with minimal weight. The double SLW3 dial closure allows for individual adjustment of pressure between the top of the foot and the toes for an even better fit. Highly abrasion-resistant, ultra-thin reinforcements ensure all-around protection of the entire upper shoe. The upper shoe features ARS (Anatomic Reticular Support) technology, which is an exoskeleton that surrounds the foot and evenly distributes pressure while pedaling. Even on hot days, excess heat is released through the mesh insert.
