This new version of compression socks, already packed with technological features, offers more innovative benefits that take care of your feet like no other sock: more comfort, more ventilation and more protection. For those who suffer from overheated soles, these high socks feature certain fibers that act as hot-spot prevention so feet don't burn and always stay cool. Freshness is also achieved by an original striped design in breathable fabric, guaranteeing light, dry and fresh feet. The toe cap has been reinforced to take even better care of big toes and nails. The tops of PRO RACING SOCKS V3 RUN 3D points on the soles of the feet, with needle therapy effect, increase blood flow through small scales so toxins don't act. On the outside of the socks, 3D points preserve bumps and limit pain and injury. The 3D points protect the ankle and Achilles tendon. The sock won't slip in the shoes held in place by the 3D points. 3D dots mean "air holes" through which air flows in and out, so your feet can always breathe. Assembled without seams or elastic, they exert no pressure on the calf or ankle. A 360° arch on the underside prevents significant impact on muscles, joints and veins. The same arch support cushions your feet and ensures stability.
