Based on the SupTraction Rubber Soul CL (CL for clipless) and with an EVA midsole the Rascal offers much more than uncompromising power transmission onto the pedal: its construction combines stiffness in the longitudinal axis with flexibility in the lateral axis and the upper. This torsional construction principle helps to prevent the foot from tilting on the pedal. Special dedicated climbing and pedal zones on the tread ensure traction both on and off the pedal. In addition, the lacing, especially the Serpen_Tie (Rascal only), makes sure the upper is perfectly closed, thus adapting to the individual needs and different shapes of the foot. Toetal_Protection (an injected toe cap) and No-Sew_Reinforcements absorb and dissipate the forces when the foot hits a rock or roots, protecting both the shoe and its contents. The asymmetrically shaped upper as well as the Ankle_Pad protect the foot on the crank side while still offering full freedom of movement. The combination of heel hold (through preshaped heel and internal padding), a supportive foot bed with a 2C (=two component) insole and cushioned midsole offers outstanding comfort. Laser cut Jet_Stream ventilation holes and fabrics ensure a balanced foot climate.
