Robust XC shoe with Triple-Density Speedlight 3D sole with a stiffness index of 10.0. Seamless unibody construction reduces pressure points. Four inserts of breathable mesh and additional micro-ventilation openings on the entire surface provide optimal ventilation. Heat-welded TPU reinforcements in the toe and heel area provide additional protection. The SLW3 Dial - the only one with gradual loosening or complete opening at the touch of a button - ensures easy access and a perfect fit.
