Secure the ideal conditions for endurance performance with the X-SOCKS® RUN SPEED TWO WOMEN and work on your personal best performance with the innovative technologies of the X-BIONIC® 4.0 product generation.
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 X-BIONIC® 4.0 generation models conceal even more patented technologies in the densely woven 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. 
Specifically designed for the slender female foot: Narrow Arrow construction and 3-Expand Ladies Stripes prevent chafing creases during movement.
