SilkLiving's 100% silk Liner Socks are a luxurious base layer to keep your feet moisture and odour-free. Perfect for those with circulation issues, they add an extra layer of comfortable warmth. Designed for wear under a thicker outer sock, it's also a super lightweight option for warm-weather day hikes and runs, or with dress shoes. To minimise wear-points on these super-thin socks, keep toenails short and avoid friction with coarse woollen socks.
