The X-Socks Run Speed ​​One are comfortable running socks. Thanks to its combination of upholstery zones and ventilating ducts, this sock is particularly suitable for medium and long-range runs. The pads on the instep and heel divert the shocks and shock waves that occur at each strong step from the foot. The patented Lambertz-Nicholson Achilles tendon protector inserts the sensitive tendon securely into a reserved area. It acts as a spacer and prevents the risk of friction and abrasion of the skin through the shoe sealing edge. The integrated ventilation channels of the Traverse AirFlow Channel System at the sole and the AirCool Stripes at the instep allow fresh air to circulate in the shoe.
