Carbon-XC-12 sole with full carbon insert in the pedal area and a stiffness index of 12.0. TPU inserts in strategic areas provide maximum traction and exceptional abrasion resistance. With the double SLW3 rotary closure, the pressure between the top of the instep and the toe can be individually adjusted for an even better fit. Abrasion-resistant TPU reinforcements on the upper shoe offer comprehensive protection. The performance regular insole provides additional support from below. Even on hot days, excess heat is released through the mesh insert. The perforated upper material ensures optimal ventilation.
