Thanks to a combination of padding zones and ventilation channels, this sock is especially well suited for wear on fast sprints or medium distances. The padding on instep and heel buffers the shocks caused by every powerful stride, and the integrated ventilation channels along the sole and instep allow fresh air to circulate in the shoe. In addition, this sock features the new, patented Lambertz-Nicholson Achilles heel protector,which creates a hollow in which this sensitive area is protected from the friction that can cause skin abrasions and blisters.
