The new ``Materials and Colors Warmth'' is made of 100% extra fine merino wool on the inside that touches the skin and 100% cotton on the outside. The large laces make it soft, warm, and thin, so when you wash it, it will shrink and become more compact, but when you wear it again, it won't feel tight and will stay soft and comfortable. You can also wear it over your real finger. Warm wool socks that are thin enough to fit into your regular shoes. The outside is made of cotton, so even though it's a wool sock, it doesn't pill.
