TRAIL ULTRA HIGH socks Merino
Discover the new TRAIL ULTRA HIGH MERINO sock, a premium trail running sock made with merino wool for natural thermal insulation and optimal comfort in cold weather. Always made in France, it combines technical performance, durability and comfort to take on the trails, from short distances to ultra-trail.
Its ultra-reinforced 3D anatomical sole improves foot stability in the shoe while absorbing shocks.
The 360° support secures the ankle and foot, while strategic reinforcements – heel, toe, Achilles tendon, malleoli and lacing zone – limit chafing and repeated impacts.
Its lightweight, breathable mesh ensures effective moisture wicking, keeping your feet dry even during intense efforts.
A wide ribbed cuff prevents the tourniquet effect while ensuring firm support, while flat seams and the asymmetrical design perfectly match the shape of each foot.
Made largely from merino wool, a natural fiber with outstanding thermal properties, the TRAIL ULTRA HIGH MERINO sock protects against the cold while quickly wicking away perspiration. Ideal for winter conditions or demanding mountain terrain, it delivers warmth, comfort and performance.
The result of the expertise of the BV SPORT R&D center and manufactured in Saint-Étienne, this sock combines innovation and French quality. Whether you’re preparing for a mountain trail in cold weather or a long run on technical paths, the TRAIL ULTRA HIGH MERINO is your best ally to push your limits, mile after mile.
Because we are committed to an eco-responsible approach, the packaging of this product is made entirely with recyclable materials.
