The Desafío Five Compression is a technical mid-distance trail running sock with an H5 height (12–18 cm above the shoe) and a compressive cuff that provides muscle support and protects against vegetation or debris on the trail. Its seamless design, hand-linked toe closure, and ergonomic +A fit ensure a precise, chafe-free fit. It features the ESP 1 plantar structure, with reinforcements at the heel, sole, and toe for enhanced cushioning. Bmax Tetra technology optimizes sweat management and reduces friction, helping to prevent blisters. In addition, the Anti-odour Base Layer mesh acts as a natural antibacterial and odour-control barrier. Ideal for technical runs lasting 1.5 to 4 hours.
