Perfect fit, perfect power transmission: Two twist closures enclose the foot absolutely homogeneously and thus ensure optimum pressure distribution. In addition, the rigid CUBE carbon outsole for maximum efficiency and the CUBE Anti-Slip System, which always keeps the heel in place. For absolute top performance! The smart mix of dirt-repellent upper material and ventilated tongue ensures optimum climate management. An asymmetrical design minimises the possible occurrence of pressure points. More safety guaranteed by reflective elements in the heel area.
