UYN Man Trekking One Merino Socks - grey/blue
(Product No.: UY-S100276-G177)
A new way to tackle your excursions: The TREKKING ONE socks offer extreme comfort thanks to the revolutionary ZEROCUFF technology. The absence of the classic cuff ensures better blood circulation, for feet that are never swollen or tired, even after hours of walking. The soft and breathable merino wool wraps the foot, keeping it warm and preventing odors from developing. The 3D protective structures on the critical areas of the foot and ankle provide 360° protection and make the sock an irreplaceable companion on your adventures.
