High-tech trail socks: the Compressport PRO RACING SOCKS v4.0 TRAIL offers superior comfort, with even better blister elimination, optimal ventilation and shock absorption for any off-road running challenge! This 4th generation trail sock is designed specifically for maximum shock absorption and support. The fabric in the forefoot is strong, but it isalso very well ventilated. It wicks away moisture and prevents irritation. The cut of the socks is higher than running models and the fabric in the instep area is thicker compared to the toe. In addition, a special knit is designed around the ankle to improve stability. The all-new toe offers a more ergonomic fit as well as improved proprioception, allowing your toes to be intuitively positioned on impact for a smooth, natural stride. The toe area is also enhanced with terry padding to eliminate blackened toenails on longer runs. The same technology is also placed in the heel area.The improved 360° arch support comes as standard. It not only promotes micro-circulation, but above all prevents the socks from twisting inside the shoe. The socks thus stay exactly in place while preventing unpleasant blisters. The outer and inner side of the ankle is covered with large sun-shaped protrusions. The Achilles tendon is protected by patented protrusions. The already well-known 3D DOTS are now complemented by the so-called FLAT DOTS, which improve ventilation. The iconic protrusions can also be found in the sole and heel area. The 3D DOTS (75%) and FLAT DOTS (25%) cushion the impact, offer better grip and improve overall ventilation. Last but not least, they guarantee micro-stimulation, which helps to improve blood flow thus delaying fatigue.An ergonomic "tongue" at the back of the top hem gives these high-tech socks a touch of comfort and sleek design that goes hand-in-hand with COMPRESSPORT's performance DNA.
