Marathon Energy 4.0 Socks black

With X-SOCKS MARATHON ENERGY, you get a head start on long distances. With even more patented technologies, the new X-BIONIC 4.0 product generation provides the decisive boost for exceptional performance. Thanks to innovative technologies, your feet are optimally prepared for the special demands of marathon running. The Air-Conditioning Channel 4.0 guides fresh air to the sole of the foot and ensures a pleasant feel-good climate. Unlike its predecessor, the channel integrated into the fabric narrows towards the top and increases the air passage. Air Guide technology and the Traverse AirFlow Channel System also provide ventilation. In the further developed model of the X-BIONIC 4.0 generation, the Lambertz-Nicholson 4.0 Achilles tendon protector increases resistance to shock, pressure and friction with its shape-optimized structures. The Suppronation Bandage also keeps endurance runners' feet stable and ready for fatigue-free performance.
