Details of the X-Socks Run Speed Two 4.0 running socks

With an innovative combination of ventilation, stabilization and protection functions, these women's socks really come into their own on longer runs. Compared to their predecessors, the models of the X-BIONIC® 4.0 generation hide even more patented technologies in the densely manufactured material. These include the newly designed Air-Conditioning Channel® 4.0 for ventilation of the foot sole.

The Instep Protector with extended Air Cool Stripes climatizes the top of the foot and protects the instep from pressure and friction. The high-performance AirFlow Ankle Pads 2.0 at the ankle and the Lambertz-Nicholson Achilles Tendon Protector 4.0 above the heel complete the comprehensive padding system.

Material 75% polyamide, 18% polypropylene, 6% elastane, 1% glass fiber
