Outstanding products can become even better: these special generation 4.0 women’s socks will convince you with greater comfort than ever thanks to their innovative combination of protective and ventilating functions. The newly designed Air-Conditioning Channel® 4.0 directs air circulation even more precisely along the soles of the feet.

The shape-optimized Lambertz-Nicholson Achilles Tendon Protector® 4.0 protects against shocks and friction. The AirFlow Ankle Pads are also knit into the dense material to ward off mechanical impacts on the ankle. The Narrow Arrow Construction and the 3-ExpandLadiesStripes are specially designed for the female foot and prevent abrasive wrinkling during movement.
