Version with semi-automatic attachment of the XLC Nanotech model. It is characterized by the same structure and very light materials as the other XLC cleats, but it stands out for the Sandvik Nanoflex® steel inserts on the front tips. Thus, strength, durability and penetration ability into hard ice are increased. The semi-automatic fastening also ensures a solid fixation on semi-rigid shoes. For ski mountaineering and telemark boots, the XLC Nanotech model with automatic binding is recommended. Sandvik Nanoflex® is an innovative alloy steel with high mechanical strength and hardness of 25% higher than normal steel alloy, which reduces the amount of metal used, significantly reducing weight while maintaining strength.
