Made in France, the TRAIL COMPRESSION is a 2 in 1 sock combining a technical foot and Selective Compression (BV SPORT patent). It is technical, comfortable, resistant and ultra-reinforced for trail running over all distances. The compression adapted to the calf improves venous return, promotes muscle, tendon and ligament oxygenation, thus optimizing performance. Its technical foot has targeted reinforcements on strategic points of the foot and stabilizing support at the ankle while maintaining optimal comfort. With its airy mesh, it quickly wicks away perspiration to stay cool and dry during outings.
