A racing bike shoe for winter rides. Made with a Primaloft 200g ECO insulation lining from recycled materials for exceptional warmth insulation and breathability. Power transfer is achieved through the NGR Air Carbon Reinforced sole with a stiffness index of 8.0. The overlapping construction made from the most innovative materials wraps the foot evenly without pressure points, helping to transfer every watt of power while minimizing energy loss. The toe is reinforced with TPU, and the closure system is comfortable and ensures an even fit through the SLW2 dial, the only one with step-by-step release. The integrated heel cup with directional fiber lining prevents heel lift, while the Arctic 4Layer insole (EVA / Aluminum / EVA / Fleece) combined with the Lasting Board heat shield (EVA / Aluminum) provides effective thermal insulation. For added safety, the 360° reflective inserts enhance visibility on the road.
