A new way to tackle your excursions: The Trekking One socks offer extreme comfort thanks to the revolutionary ZEROCUFF technology. The absence of a classic cuff allows for better blood circulation, keeping your feet from swelling or getting tired, even after hours of walking. The soft and breathable merino wool envelops the foot, keeping it warm and preventing the formation of odors. The 3D protective structures at critical points of the foot and ankle provide 360° protection, making the sock an indispensable companion for your adventures.
