BLACK CYCLING/RUNNING SOCKS In cycling and running, socks are essential and very important, as is their quality! Not only for preventing friction inside shoes and aiding blood circulation, but also for managing and wicking away moisture from the legs. Our socks are specifically developed for sports. They are made of a soft, breathable technical fabric with different elasticity (compression) zones. (On the diagram: 1 light compression - 3 self-adjusting elastic zones) The specific structure of the fabric allows it to adapt perfectly to the shape of the foot and calf without wrinkling. Specific areas made of highly breathable fabric serve to wick away perspiration (zones 2 on the diagram). The top of the sock features a non-compressive elastic band to ensure the sock always stays at the same height on your calves. These cycling/running socks measure 10 cm in height from the ankle. Made in Spain.
