These are—without a doubt—the best quality socks money can buy! These cashmere socks are comfortable, luxurious, and amazingly soft in their content, with a non-binding top which won't restrict leg circulation. We've combined the familiar feel of cashmere with our staple merino wool to bring you an affordable sock without compromising quality. Cashmere socks are made from wool from a Kashmir goat. Cashmere wool is typically softer, lighter, and more insulating than sheep's wool. In addition, it has a texture that feels like silk. The difference between this and the plain cashmere are these are ribbed along the foot and the leg, and they are slightly lighter in weight, which makes them more suitable for dress shoes and formal occasions. Please note that due to the high percentage of cashmere in these socks we recommend that they are hand washed and hang dried.
