With only 50 pairs available, these socks are limited edition. So don\'t waste time and get yourself a pair of these cool garments.This is a unisex Running sock with medium compression. Because of this the blood circulation gets stimulated constantly. This ensures a comfortable fit throughout any race.The fabric is breathable and the lateral grids make sure moisture has a way out, which keeps the foot dry. Blisters are less likely because the sock has no seams. The heel and toe are reinforced with cotton for a more comfortable fit. During testing the socks turned out to be perfect during both training and competition. They offer optimal performance on asphalt, track and trail.The Softair +Plus tissue transmits a natural, soft and silky touch to the body. The elastic fiber provides great comfort, freedom of movement and adaptability to the foot. It is also thermoregulative; in colder weather or low performance, it acts as thermal insulation. On the other hand, in warm weather or during high performance, the fabric acts as a refrigerator and keeps the foot at the ideal temperature for the race.
